May I point out that I am developing a replacement
for SMACC. I expect my parser generator to be easier to use,
faster, and build smaller parse tables than SMACC.
I don't expect it to be ready soon and suggest that it not be used
for as widespread an application as the parser for Squeak until
it has been in the field for a while so I expect that you will
proceed with using SMACC.

The syntax for my parser generator will be different from SMACC
so SMACC users would need to rewrite their grammars in order
to switch to my parser generator tool.
