Sounds great to me.

This is sort of a tangent, but on the subject of SmaCC:

Because SmaCC is MIT-licensed, as we make any changes to the SmaCC 
package (as part of Version 4 or anything else), we should keep the 
original MIT-licensed SmaCC package as-is, and have a separate SqueakL 
licensed package for Squeak related changes.  This is also true for 
SUnit, which is the only other non-SqueakL package in the base release.
