For example all of these give a syntax error: ~~~ def foo(class); end def foo(def); end def foo(if); end # ... other keywords too ~~~ The reason is that there's no way to refer to these names because they are keywords. However, we can use these names for keyword arguments. All of these work: ~~~ def foo(class: 1); end def foo(def: 1); end def foo(if: 1); end ~~~ But I think they should give a syntax error, because for example I can't refer to the argument "class" in the first line (same reason why the first snippet gives a syntax error). -- https://bugs.ruby-lang.org/ Unsubscribe:
