Bug #15647
Updated by nobu (Nobuyoshi Nakada) about 5 years ago
"`in`" "in" is a reserved reversed keyword and thus can't be accessed directly anyway. e.g. the following is a syntax error: ```ruby def `def m(in:); p in; end; m(in: 1) ``` 1)` And as usual, doing `in = 1` doesn't work. "`in`" "in" could still be passed as a keyword argument if using some kind of catch-all, e.g. `m(args)`, `m(*args)`, m(args), m(*args), etc. Source: https://twitter.com/drbrain/status/1104152696339087361
