|
||||
interpolation.
|
||||
|
||||

* intern.h: prototypes; rb_is_junk_id, rb_str_dump, rb_str_intern
|
||||
|
||||
* object.c (sym_inspect): escape and quote for non-alphanumeric
|
||||
symbols.
|
||||
|
||||
* parse.y (dsym, tokadd_string, yylex): extended symbol literals.
|
||||
|
||||
* parse.y (rb_is_junk_id): added.

||||
|
||||
* string.c (rb_str_dump, rb_str_intern) : make extern.
|
||||
|
