They are good, but in Python, making them slower than a good and robust
C implementation.
I wonder if porting them from Python to Cython (the new pyrex) to get
the good and robust C implementation would be a good solution.
I do not know anything about Cython, but if the code it generates is
actually maintainable (means: well-structured, readable and easy to
modify), it might be worth a try.
That totally defeats the purpose of Cython. One maintains the Cython
code. The C code is just an intermediary step in compiling an extension
module. The intermediate C is easier to follow than that generated by
other high level languages, but one would not want to alter it. Have a
look at pypm.c for an example generated with Pyrex.
But I do have my concerns. Cython is not a stable language. It may
change to remain compatible with Pyrex, which is still in alpha
development. This just means keeping ones Cython compiler current. Also
Cython doen't support variable length types, tp_itemsize not zero. This
might be of concern if vector size is an attribute.
