I don't know if it is significantly faster or not.  I wasn't guided by
a specific goal; I just spent an afternoon seeing if the profiler
showed anything obvious.  There were a couple of hot spots that I
fixed, but nothing dramatic.

I actually haven't compared old times and new times.

Do you have specific performances goals that could be addressed?

What kind of tree does the Wing IDE code produce?  I saw the
announcement, but haven't had time to look at it.

Ok.
