In many case the generator will create from MyClassX some MyClassXImpl or
equivalent that extends the original one, bu not REPLACE it as Java source.
This is what I mean by "pre-process".

For example, to implement a AOP framework I'd like to instrument all calls
to some method. For this reason I'd like a generator / pre-processor to
check the source files and detect the matching pointcuts to add some adived
code. Many other example can apply, including annotation processing for
declarative coding (ex : @Property annotation to automagically introduce the
required PropertyChangeListeners)

I never tried it myself, but I'n not sure a generator can REPLACE the
original Java Source. I may be wrong but I also thing the generated code is
only available when using   GWT.create(), making the code less testable
(with standard junit, not GWTTestCase) and fully GWT-dependenant.

Cheers,
Nicolas
