The `__id__` method implemented in the C function has `MRB_ARGS_NONE()` specified, but it is also effective in the following cases. ```ruby p nil.__id__ opts: 1 rescue p :a p nil.method(:__id__).call 1 rescue p :b p nil.method(:__id__).call opts: 1 rescue p :c p nil.method(:__id__).to_proc.call 1 rescue p :d p nil.method(:__id__).to_proc.call opts: 1 rescue p :e p nil.method(:__id__).unbind.bind_call nil, 1 rescue p :f p nil.method(:__id__).unbind.bind_call nil, opts: 1 rescue p :g p nil.__send__ :__id__, 1 rescue p :h p nil.__send__ :__id__, opts: 1 rescue p :i ``` After applying this patch, all items will output symbols in the same way as CRuby. For this purpose, add `MRB_PROC_NOARG` to `struct RProc::flags`.
