No. Logical operators short circuit, but you do not do associative and communicative math with logical operators.

That's not my point. My point is that there are already operators where EXPR1 OP EXPR2 may cause one of the expression to not be evaluation, and people don't find that strange. Or inconvenient.

And in languages with lazy evaluation, this is common.

Hmm. I though lazy evaluation meant that the value wasn't calculated until needed.

If f() is a lazy evaluating function and I call it, it will give a result. The only way it wouldn't get called in the statement

result = f(a) * g(b) + h(c);

is if the compiler took it upon itself to override my explicit request to call it. If perl ever starts doing that, I'm gonna use VB!
