The version of MC that I just posted on SM should make what we were 
discussing easier.  I've made two changes: first, when building a 
snapshot, each class in the package gets to return a collection of 
#classDefinitions rather than a single #asClassDefinition.  Second, 
when reading the .st snapshot file, any unrecognized doIts get the 
chance to be handled by a subclass of MCDoItParser.  New subclasses 
must:

- implement #pattern on the class side to return a string that will be 
#match:ed against the doIt.
- implement #addDefinitionsTo: .  This should parse the 'source' string 
inst var into any number of Definition objects and add them to the 
collection that is passed in.

I'll probably write up a wiki page soon that describes all the steps 
necessary for adding custom definitions like this.
