Comment (by dimpase):
It is correct that a part of GAP code computes elements e and nu of
GF(q^2^) described in the docstring. One can do this in Sage with Sage
finite fields, but converting the results to GAP finite fields is painful
and error prone (and slow). (Or one can use libgap to do these
computations with GAP objects using Sage syntax - but then letting these
objects be known to GAP's libgap to be used in `function_factory` call is
a painful hack, as far as I can see).
Anyway, it's done, it works very fast, and I don't see why this needs to
be changed. GAP language is very easy, too, as easy as Python, if not
easier.
One major shortcoming of `function_factory` is that it does not allow
comments in GAP string, as it's just one line of GAP code, and GAP does
not have C-like comments, i.e. `a=1; /* blah */ b=2;` is not possible. I
can add more comments if needed (out of the code body).
PS. last but not least I ideally should take at least few days away from
keyboard/mouse, as I seem to have a case of "mouse elbow", a.k.a. RSI...
