I used python.el/wy to get started with the wisent parser a couple weeks ago, that help a lot. There INDENT/DETEND tokens are a nice solution. Meanwhile after having worked for some weeks with wisent/semantic I think that using an expandfull0 macro (=EXPANDFULL with depth=0 instead of 1 in the call to semantic-parse-region) is just the right thing to do. Standard routines and macros are rather designed for C-like languages, which is fine as those are the big majority, and the overloading mechanism is a nice design to cater to differently structured languages like python or Fortran. But nevertheless being new to cedet this got me a bit confused. (By now I have also discovered that declare-macro allows to declare language specific macro...)

Thanks for the support. I am almost there, I still like to have some basic support for formatting/summarising, completion and importing from other files.
