in reply to Quantum Weirdness and the Increment Operator

You can follow the results by realizing that post-increment returns a value, while pre-increment returns an alias to the variable. That makes subsequent operations of high enough precedence turn up in pieces that have already been evaluated.

There is no reason that perl must do it that way. Perl could do away with the C restriction, which is there for good C reasons, and return values for each increment operation. That would make perl do what you expected. But for forseeable perl, as has been said (and shouted), "Don't do that!"
