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.
