Watch out: unlike the sequencing implied by the comma operator, there's no sequence point between the arguments to a function, and they may be evaluated in any order, or even have their evaluation interleaved.

@lxo @rayslava @Revertron Thanks, you probably saved me some time there, as I hadn't yet decided to use it in a non-trivial case (so far I've used it do to `++i, ++j;`);

trying to get too clever with side effects and sequence points of little visibility is probably bad practice anyway, except when writing code for obfuscated programming contests

the fact that the comma operator sequences the right operand after the left operand, while the argument separator with the same spelling ',' doesn't, is a somewhat common source of undesirable surprises
