03:36 PM Feature #15836: [Proposal] Make Module#name and Symbol#to_s return their internal fstrings

It copies it - strings and symbols aren’t the same thing so it couldn’t jus return the symbol again. -
02:54 PM Feature #15836: [Proposal] Make Module#name and Symbol#to_s return their internal fstrings
- is the String returned by rb_sym2str not always frozen?
how is the GC handling in case the Symbol was a dynamic generated one?
wouldn't that remove the string that got returned from rb_sym2str too? -

In many codebases, especially Rails apps, these two methods are the source of quite a lot of object allocations.
