    raised for any compilation-related errors.

    (originally, I wanted to subclass this from compilationError,

    and raise different error for code generator issues (i.e. method too

    big, etc.) But all users of the parser in the system (RB-stuff, Lint stuff,

    fileIn etc.) always handle the ParseError, and I don't want them to be forced to change.

    So we subclass the codeGenerator issues from this one.
