Personally, I prefer "if (!foo)" over "if (foo == nil)", because the
latter has the hazard of a typo that compiles. You can lose a fair
bit of time staring at "if (foo = nil)" before you spot the mistake.
There is a GCC warning to help you with that, but in addition, you can
learn to type:
if (nil == foo)
Problem solved! :-)
I personally much prefer to have if-statements that clearly evaluate
to a boolean value. More intention revealing, and to me that's more
important than being terse.
