+
+ I did write it a long time ago, it is too complicated for what it
+ does. You can see an example in the PyHorizontal.cpp file and
+ look at PyHorizontal_create(). It is very dumb and tedious
+ programming. I intend to review it thoroughly when migrating
+ to Python 3. Basically it build the "signature" of the function
+ and is followed by a big "if" afterwards.
+ The Python "wrapper" is not something I'm very proud of as it
+ is only a big bunch of C macros. I'm not happy with the *way*
+ the code is generated, but on the other hand, I am happy with
+ the *generated* code and the fact that I can finely tune it.
+ I will try to make a more intensive use of C++ templates.
+ But not as much as in Boost as it becomes very, very slow to
+ compile (it's the reason why the Qt team abandoned it in favor
+ of another interface generator).
