Since disable.h was removed, enable.h was the only remaining dispatch target from presym.h. Inline its contents into presym.h and delete the now-redundant enable.h. Also define _2 backward compatibility macros in terms of the standard macros. Co-authored-by: Claude <noreply@anthropic.com>

* replaced by the symbol ID using the following macros.
|
|
*
|
|
* MRB_OPSYM(xor) //=> ^ (Operator)
|
|
* MRB_GVSYM(xor) //=> $xor (Global Variable)
|
|
* MRB_CVSYM(xor) //=> @@xor (Class Variable)
|
|
* MRB_IVSYM(xor) //=> @xor (Instance Variable)
|
|
* MRB_SYM_B(xor) //=> xor! (Method with Bang)
|
|
* MRB_SYM_Q(xor) //=> xor? (Method with Question mark)
|
|
* MRB_SYM_E(xor) //=> xor= (Method with Equal)
|
|
* MRB_SYM(xor) //=> xor (Word characters)
|
|
*
|
|
* For `MRB_OPSYM`, specify the names corresponding to operators (see
|
|
* `MRuby::Presym::OPERATORS` in `lib/mruby/presym.rb` for the names that
|
|
* can be specified for it). Other than that, describe only word characters
|
|
* excluding leading and ending punctuation.
|
|
*
|
|
* These macros are expanded to compile-time integer constants.
