Re^3: Equivalency of Code

[DrHyde]

The point is that $x++ and $x += 1 don't just fiddle with the value of $x. Those statements also have values themselves. If a bit of code is to be equivalent to another, then it needs to both have the same side-effects and the same value as the other does.

I try not to think about operator overloading or tieing :-)

[Anonymous Monk]

The statements are presented where in void context - and in void context, there's no return value.
