The reason why the filename thing is enforced is because:
1- this file needs to be generated into ax_enums.h/cc for gyp reasons (otherwise
changes won't get picked up properly IIRC)
2- the namespace determines the generated file names, not the original file name

I'd rather not introduce another annotation for this special case. Instead we
can change point (2) to generate into a file based on the original filename
rather than the namespace.

Unless it already does. I can't remember.

That's exactly it. The cc generator and friends use the "unix_name" which is
just the namespace to create the various filenames.

I can remove the annotation and just leave my changes to use the short filename
as opposed to the unix name. Is that what you're saying?
