This gives a warning, at least.

Works for me....

I first discovered this is possible when RubyLexer tripped over a
specimen of code that was using it. Little mysteries like this were
part of what made RubyLexer such an, ah, joy to write. (Yeah, that's
one word for it.)

Now I use this sometimes myself, mostly to create more test cases for
RubyLexer, since def headers in particular are tricky. It can be
convenient when playing around in irb.
