python

I used a global function pointer op, so that when op = add, it operates
as add, when op = minus, it operates as minus. I used a function
choose_op() to set op = add or minus. It works if I call choose_op()
inside other function exposed in python. It reported a error when I used
bjam to compile it if I exposed it into python.

Any suggestion will be appreciated. Thanks in advance.

[Nat] How were you planning to have the client Python code pass to
choose_op() a parameter of type 'float (* method)(float a, float b)'?

Maybe you could publish to Python a wrapper function that accepts a
string or something. On receiving "+", it would call choose_op(add), and
so forth.
