Hallo - I had a GAP variable called F, which was either equal to 0, or to

a finitely presented group.

Naturally, I put

if F<>0 then ....

but I was rather surprised when this caused GAP to try and calculate the order

of F (which was pretty hopeless, since F was infinite).

Is this intentional behaviour?

I was asking if F was equal to the integer 0, and expected to get an immediate

"no" as an answer.
