Yup, that's exactly how it works. There are several visitor classes 
that iterate over the definitions in a package to produce various file 
formats: .st, .mc, .mcv, .mcz.

There are corresponding reader classes for each format as well, which 
consume a stream and produce definitions. We used to do this by 
evaluating chunks in a restricted environment, but it turns out to be 
much better to just parse each chunk ourselves.
