[Cuis-dev] Subtle Parser bug?

[Phil B]

Hi Nico,

The bug is in your source code ;-)  The self is due to the fact that you
have 'foo.' instead of just 'foo' (i.e. you don't need the $. to terminate
your args and any empty expressions in the body, which the trailing $. will
be parsed as, will result in a self).

Thanks,
Phil
