Just a bug in the grammar.  I fixed it.

Can't do it, the parser chokes on allowing either '*' or 'expr' because 
'expr' can start with a star (left operators suck).  Pick a different 
character...

There are still problems with partial array initializers not doing the 
right thing, I'll go fix that.
