[Backport #21186]
2025-02-25[Bug #21153] Add missing op-assign to top const in `command_asgn`Nobuyoshi Nakada
It was defined in `arg` only; add that pattern to `command_asgn` as well.
2025-02-13merge revision(s) fb18bb183c24ca82b8f114ed090d62bd69b5df84: [Backport #20989]Takashi Kokubun
[Bug #20989] Ripper: Pass `compile_error` For the universal parser, `rb_parser_reg_fragment_check` function is shared between the parser and ripper. However `parser_params` struct is partially different, and `compile_error` function depends on that part indirectly.
2024-12-23Revert "[Bug #20965] Define `it` like an ordinary argument" (#12418)Takashi Kokubun
Revert "[Bug #20965] Define `it` like an ordinary argument (#12398)" Reverts ruby/ruby#12398 as per https://bugs.ruby-lang.org/issues/20970#note-6 and https://bugs.ruby-lang.org/issues/20965#note-7. We need more time to design the intended behavior, and it's too late for Ruby 3.4. Notes: Merged-By: k0kubun <takashikkbn@gmail.com>
