This is a common issue for all languages.
I dislike the changed style because it is unnecessarily more verbose.
I've had some conversations on swig-devel trying to get the deprecation
reversed. I've not made much progress convincing the SWIG developers.
We have two options, as I see it:
1) Put up with the increased unhelpful verbosity of replacing:
%typemap(python, ...) ...
%typemap(perl5, ...) ...
%typemap(ruby, ...) ...
with:
#if defined(SWIGPYTHON)
%typemap(...) ...
#elif defined(SWIGPERL)
%typemap(...) ...
#elif defined(SWIGRUBY)
%typemap(...) ...
#endif
2) Decide that we find the deprecated syntax useful, and send an email
endorsed by group consensus, and signed "The Subversion Project" to
the SWIG developers, requesting the deprecated feature be
undeprecated. Have every Subversion developer in favour reply to the
initial posting to swig-devel, affirming their agreement.
So, your thoughts?
Max.

Either of the options are acceptable. I want to hear other
thoughts of other SWIG related committers.
