Yup - that's a problem all right.

We could certainly go with a new syntax, such as you colon idea (which 
is nice and terse), or using something like

   rescue  SyntaxError into e

which is longer but perhaps more readable.

Or maybe we could bite the bullet and make it a syntax error to have
method names start with an upper case letter, thus allowing the Xxx(e) 
syntax _and_ cutting out a class or ambiguity problems in normal code.

Would that be a major problem to enforce?
