Well, a set extremely similar and in-sync (at least loosely) to the C
contants, so while technically different constant names, there is a very
easy rule to convert from C to Perl: drop the GIMP_. The gimpdoc program
already converts between C and Perl method syntax, so it could just be
extended to drop DIMP_ for Contants, too.

Constants are hardcoded in Gimp.pm, and there is a program named insenums
which will replace these in-place.

Not so quickly ;) Changes in these enums will immediately break existing
scripts, which is a very bad thing. Also, some wild renaming during
the 1.3 era resulted in duplicated constants that had to be resolved
differently, so this usually involves some manual work, which is why the
script has to be run manually, too.

I am not sure wether I understand your concept of "sameness". To me,
GIMP_RGB_IMAGE, RGB-IMAGE and RGB_IMAGE is exactly the same constant, just
as gimp-drawable-add-layer is the same as gimp_drawable_add_layer and

This is the situation with perl right now, although that line is probably
hard to find, but people don't read this type of documentation anyway,
they just look at other scripts, and then consistency really pays off.
