!SourceChangedDuringLoad commentStamp: '<historical>' prior: 0! If signalled, the source code that Monticello ultimately loaded into the system is different from the code it was asked to load, due to one of two things:

- the presented code had syntax errors that the user corrected at load time - the presented code had underscore assignments that were changed to := at load time

method: something to describe the method that changed. For MCPackageLoader1b, it is an MCMethodDefinition. For MCPackageLoader2, it is a MethodEditor!

!FixUnderscores2 commentStamp: '<historical>' prior: 0! I am a utility to change underscore assignments to :=. I only understand source strings for now, and don't yet work on already loaded code. I will probably be moved to another package later (like SystemEditor)!
