Comment #12 on issue 3184 by pr...@goodok.ru: 0**I giving wrong answer
http://code.google.com/p/sympy/issues/detail?id=3184
I am completely agreed that 0**0 is very useful for combinatorics aims.
btw, it is used while series implementation
https://oeis.org/A081294 (FORMULA section)
I don't know that it is directly extended for complex coefficients.
Possibly can.
http://en.wikipedia.org/wiki/Binomial_coefficient#Two_real_or_complex_valued_arguments
But I am not sure that combinatoric and 0/0 in complex field topics must
necessary be mixed together. Contrariwise, (it my opinion) the things must
be distinguished as more as it is possible. And if I calculate expression
in extended complex and sympy silently substitute 0**0 with 1, I must be
warning about it. At least.
