Hi everyone,

I'm quite sure that this question has already been answered but I couldn't find any satisfactory explanation (my bad).

I'm wondering why the following expression

 sum(0^k, k = 0 .. 0);
yields 0 as result while

0^0;
returns 1

and 

sum(1, k = 0 .. 0);
also return 1.

I understand that 0^0;

is an indeterminate form so that its evaluation is a matter of convention but Maple's approach...
