* hash.c (rb_hash_values_at,env_values_at): ditto.
* re.c (match_values_at): ditto.
* struct.c (rb_struct_values_at): ditto.
* re.c (match_select): add iterator behavior.
* ext/curses/curses.c, ext/digest/sha2/sha2.c, ext/iconv/iconv.c,
ext/racc/cparse/cparse.c: include "ruby.h" at the top to shut up
"_FILE_OFFSET_BITS redefined" warning on Solaris.
* class.c (rb_class_protected_instance_methods): now gives
warnings to show migration path. The default will be reversed
on Jan 2004.
* numeric.c (num_step): "1.1.step(1.5,0.1)" to work.

warnings to show migration path.
* lib/delegate.rb (Delegator::initialize): instance_methods
etc. now recurse by default. need to specify false.

* hash.c (env_shift): ditto.
* hash.c (env_invert): ditto.
* hash.c (env_replace): ditto.
* hash.c (env_update): ditto.
* array.c (rb_ary_join): dispatch based on "to_str".
* array.c (rb_ary_times): ditto.
* array.c (rb_ary_equal): ditto.
* process.c (rb_f_exec): dispatch based on "to_ary".
* eval.c (umethod_bind): exact class match is not required. relax
the restriction to subclasses.
* eval.c (rb_eval): call "inherited" before executing class body.
* class.c (rb_define_class): call "inherited" after defining the
constant.
* class.c (rb_define_class_under): ditto.
* eval.c (massign): expand first element if RHS is an array and
its size is 1, and LHS has concrete assignment target (i.e. LHS
has target(s) other than *var).
* eval.c (massign): avoid unnecessary avalue/svalue conversion.
* eval.c (rb_yield_0): ditto
* array.c (rb_ary_update): do not allocate unused array if rpl is
nil (i.e. merely removing elements).
* io.c (io_read): should resize supplied string if it's shorter
than expected.

st_compare_func_t, st_hash_func_t and st_each_func_t.
* st.h, st.c: Do explicit function declarations and do not rely on
implicit declarations. On such platforms as IA64, int argument
values are NOT automatically promoted to long (64bit) values, so
explicit declarations are mandatory for those functions that
take long values or pointers. This fixes miniruby's coredump on
FreeBSD/IA64.
* class.c, eval.c, gc.c, hash.c, marshal.c, parse.y, variable.c:
Add proper casts to avoid warnings.

* array.c (rb_check_array_type): new function: return an array
(convert if possible), or nil.
* string.c (rb_check_string_type): new function: return a string
(convert if possible), or nil.
* numeric.c (rb_dbl_cmp): returns nil if values are not
comparable.
* numeric.c (fix_cmp,flo_cmp): use rb_num_coerce_cmp()
* bignum.c (rb_big_cmp): ditto.
* numeric.c (rb_num_coerce_cmp): new coercing function for "<=>",
which does not raise TypeError.
* numeric.c (do_coerce): can be supress exception now.
* object.c (rb_mod_cmp): should return nil for non class/module
objects.
* re.c (rb_reg_eqq): return false if the argument is not a
string. now returns boolean value.
* class.c (rb_include_module): argument should be T_MODULE, not
T_class, nor T_ICLASS.
* eval.c (is_defined): "defined?" should return "assignment" for
attribute assignment (e.g. a.foo=b) and indexed assignment
(e.g. a[2] = 44).
* parse.y (aryset): use NODE_ATTRASGN.

really a module, whose methods must be safe for reciever's type.
* eval.c (rb_eval): nosuper should not be inherited unless the
overwritten method is an undef placeholder.
* parse.y (primary): allow 'when'-less case statement; persuaded
by Sean Chittenden.

public_method_defined?, private_method_defined?,
protected_method_defined?
* object.c (rb_obj_public_methods): new method
Object#public_methods.
* class.c (ins_methods_i): Object#methods should list both public
and protected methods.
* class.c (rb_class_public_instance_methods): new method
Module#public_instance_methods.

self-assignment.
* class.c (rb_make_metaclass): metaclass of a superclass may be
NULL at boot time.

* eval.c (ruby_run): should set toplevel visibility again here.
* eval.c (rb_eval): should not rely on ruby_class == rb_cObject
check. Besides allow implicit publicity for attribute set
methods.
* parse.y (primary): need not to check class_nest, just set
whether method is an attrset or not.
* string.c (rb_str_each_line): p might be at the top of the
string.
* class.c (rb_make_metaclass): class of metaclass should be
metaclass of superclass, unless class itself is a metaclass;
class of metaclass of metaclass should point back to self.
eh, confusing, isn't it.
* class.c (rb_singleton_class): check if its class is singleton
AND attached to self.
* eval.c (rb_eval): should define class/module under ruby_cbase.
* eval.c (rb_eval): should set class/module path based on
ruby_cbase, not ruby_class.
* eval.c (module_setup): use ruby_cbase instead of ruby_class.

* marshal.c (w_extended): should allow marshaling of object which
is extended by named module.
* class.c (rb_make_metaclass): super may be T_ICLASS, need to skip.
