in thread Incrementing a Hash Value

I'm definitely not qualified to argue whether this behavior should be considered 'undefined', but I haven't seen any pointers to documentation that says that it is.

perlop is written in a language which is a little less than explicit than Perl, but it doesn't say that ++ and -- work exactly as in C.

In fact, perlop says:
"++" and "--" work as in C. That is, if placed before a variable, they increment or decrement the variable before returning the value, and if placed after, increment or decrement the variable after returning the value.

In other words, the auto-increment operator works as in C in the specific way mentioned. (perlop then goes on, in the next paragraph, to explain one way in which the perl implementation differs from C.)
