Is your feature request related to a problem? Please describe.

Ruby disallows that and blows up with a syntax error. At least JRuby does that. Not sure what MRI does.

I was surprised to see that RuboCop passes with a file containing that.

Describe the solution you'd like

A cop that flags that as an error.

Describe alternatives you've considered

None.

Additional context
