I had reason to want a generic in the method's return type:

%type Token<JavaTokenType>

JFlex kindly tells me that '<' is an unexpected character. I had to
work around it by defining a subclass that extends the desired type.

I wanted generics with %implements, too, but interestingly JFlex has
no trouble with that. Although I haven't run into a reason to do the
same for %extends, it has the same limitation as %type.

If you decide to support generics, then I'd preemptively point out that
there are several other weird characters that could potentially occur
too: space, comma, question mark, ampersand.

(Thanks for JFlex!)

Took a while, but I've now implemented this in revision 356.

Generics syntax for %class and the new %ctorargs is supported as well.

Cheers,
Gerwin
