Previously, on a Regexp without a fixed encoding (which is most common), we would recompile and overwrite the compiled regex. This meant that if we flip-flopped between two or more encodings we would need to continuously recompile the sa...jhawthorn (John Hawthorn)
Since rb_enc_str_coderange(str2) is called first, str2_cr is never UNKNOWN and rb_enc_cr_str_buf_cat returns it unchanged, so writing it back to str2 is redundant. It is also an unsynchronized write to str2, which may be a frozen string ...jhawthorn (John Hawthorn)

Since 44fff96b0b (Attach a box classext to its class before filling it in) the half-built classext is reachable by the GC while it is being filled, but the new m_tbl was only stored on it once it was complete, and for an ICLASS the GC on...jhawthorn (John Hawthorn)
Under refinements, vm_caller_setup_arg_block caches the func it makes for `&:sym` in the cref's refinements table. The cref belongs to whichever Ractor ran `using`, usually main, but any Ractor calling a method defined there reached the ...jhawthorn (John Hawthorn)
