Got it, thanks!

Got it, thanks! Very useful file.

 I’m curious about this comment in that file:

# This conflicts with the C++ bool type, and unfortunately
# C++ is too liberal about PyObject* <-> bool conversions,
# resulting in unintuitive runtime behavior and segfaults.
#    ("bool",    "PyBool_Type",     []),


I can believe it. Bool is a mess in C, twice as bad in C++ ..
and exponentially screwed up in Felix :-)

The problem is compatibility in bindings..

The thing is I did translate bint in pxd files to Felix bool,
which is a bit, embedded in a 64 bit unsigned int .. different
to both C and C++ :-)

Now you have me worried!  Any more
detailed explanation of this issue?
