Why Timothy Cain creator of Fallout left Fallout 2 during development

x <= y isn't two tests.

In a low-level sense, branch-if-greater-or-equal is one instruction even on RISC machines — and not one any more "complex" than branch-if-greater.

In an abstract boolean-algebra sense, x <= y is the same as !(x > y).

i.e. two tests, or perhaps i should say logical operations. i'm not saying don't use '<=', but do check that it is doing what you think it should.

Let me put it another way: the following are the same code:

if: x <= y, do: foo(), else: nothing()

if: y < x, do: nothing(), else: foo()

Shouldn't the last statement be:

if: y > x, do: nothing(), else: foo()

Nope, order of evaluation might matter with impure code.

How exactly? Well there is an extreme case where x and y are volatile but even then the order is implementation defined so I can't see a world where it matters.
