Are you proposing a 2nd SWIG Guile module in addition to the current module?

I am no guile user, so can't help on the Guile side. The guile SWIG 
module is suffering neglect and doesn't seem to work with modern 
versions of Guile - the test-suite fails for me. Only very rarely are 
there Guile queries on the SWIG mailing list, so suspect it isn't used 
much. Would it make sense to drop the older Guile interface altogether 
and just use Guile 2? BTW, there is the swig -scm option for guile 1.6+. 
So there seems to be GH and SCM and now guile 2 API... does that sound 
right that there are so many C interfaces or is your Guile 2 interface 
just SCM?
