But `forward-word' will jump to the end of the next word then, since 
"begin" as a whole would have non-word syntax.

Yes, that's not what my suggestion was.

I would've put ")" at the end of "end", but otherwise, that is it. I 
didn't expect it to work with current open/close parens syntax classes, 
though: "string quotes", in similar circumstances, doesn't.

The problem with font-lock is important. Maybe we need a syntax class 
that would mark text as symbol (or word) constituent (or delegate to the 
buffer syntax table), and at the same time mark them as parenthesising 
construct.
