Syntax mis-highlights function parameter type

[derekwyatt]

The default value for parameter f is mis-highlighted.

This is caused by a royal PITA. The brackets aren't actually set up as a region. If they were, then I could say that => follows that region and keep things to the scope of types. But, I can only have one region defined that begins as (, and that causes problems. I could use a match but you can't easily (or at all?) have matches contain the same matches recursively, like you would with regions. I could go on... but it's easier to sum it up as a PITA.
