Language Spec.

- def foo; .. rescue .. end
- compile time string concatenation, "hello" "world" => "helloworld"
- rescue modifier; a rescue b => begin a rescue; b end
- %w(a\ b\ c abc) => ["a b c", "abc"]
- objectify symbols
- class variable (prefix @@)
- rescue RuntimeError in err ??
* operator !! for rescue. ???
* objectify characters
* ../... outside condition invokes operator method too.
* ... inside condition turns off just before right condition.???
* package or access control for global variables??
* named arguments like foo(nation:="german") or foo(nation: "german").
* method to retrieve argument information (needs new C API)
* multiple return values, yield values.  maybe incompatible ???
* cascading method invocation ???
* def Class#method .. end ??
* class Foo::Bar<Baz .. end, module Boo::Bar .. end
* def Foo::Bar::baz() .. end ??
* I18N (or M17N) script/string/regexp
* Fixnum 0 as false ????
* discourage use of symbol variable (e.g. $/, etc.) in manual
* discourage use of Perlish features by giving warnings.
* `exception' method to be alternative for `$!'. ??

Hacking Interpreter

- use eban's fnmatch
- RUBYOPT environment variable
- alias $defout $>
- retrieve STACK_LEVEL_MAX from users' limit.
- remove end_proc registered out of require only
- all object made freezable
* non-blocking open (e.g. for named pipe) for thread
* avoid blocking with gethostbyname/gethostbyaddr (use fork ???)
* objectify interpreters ???
* remove rb_eval() recursions
* syntax tree -> bytecode ???
* scrambled script, or script filter
* setuid ruby
* performance tune for in-block (dynamic) local variables.
* generational GC ?? (is it possible?)

Standard Libraries

- hash[key] = nil does not remove entry; hashes may have nil as the value.
- hash.fetch(key) raises exception if key is not found.
- Array#{first,last,at}
- Dir.glob(pat){|f|...}
- sprintf/printf's $ to specify argument order
- Dir.glob("**/*.c") ala zsh
- Remove Enumerable#{size,length}
- Array#slice, Array#slice!
- String#slice, String#slice!
- Marshal should handle generic instance variables.
- debugger for thread programming
- SyntaxError, NameError, LoadError and NotImplementError are subclasses of
  ScriptError<Exception, not StandardError.
- Thread::start gives arguments, not a thread object to the block
- regexp: (?>..), \G
- Struct::new([name,]member,...)
- IO#reopen accepts path as well
- Kernel#scan
- call initialize for builtin classes too (not yet: Regexp, Class, Module)
- performance tune for String's non-bang methods.
- 'w' template for pack/unpack
* String#scanf(?)
* Object#fmt(?)
* Integer#{bin,oct,hex,heX}
* Time::strptime
* Integer[num], Float[num];  Fixnum[num]?
* method to retrieve non-number trailer for to_i/to_f.
* Stream or Port, abstract superclass of IO ?
* String#{pred,prev}, String#downto
* optional stepsize argument for succ()
* Ruby module -- Ruby::Version, Ruby::Interpreter

Extension Libraries

- FastCGI ruby
* ptk.rb pTk wrapper that is compatible to tk.rb
* Berkeley DB extension
* BitVector

Ruby Libraries

- net/http.rb
* add uri.rb
* urllib.rb, nttplib.rb, etc.
* format like perl's

Tools

- extension library maker using SWIG
* freeze or undump to bundle everything

Misc

- publish Ruby books
* publish Ruby books in English

Things To Do Before 1.6

* fix spec. for the following:

  * alternative for $! (exception? in? into? =>?)
  * alternative for interator?
  * regex - /p, /m
  * odd? even?
  * mkmf.rb - create_makefile("net/socket")
