Re: Re: Re: Re: Incrementing a Hash Value

Only what the standard, or the documentation, guarantees is valid to count on. Everything else should be considered a quirk of the implementation.

Shouldn't there be a lot more documentation, then? Increments and decrements are not the only things being documented vaguely.

Yep, there should be, or at least more specific docs on how things should act. Perl is awfully fuzzy about the behaviour of a lot of things. (Witness the fact that perl only recently nailed down the behaviour of numeric operations) As a for example, in this: `$a = $a + $a++;` [download] what should $a equal at the end? And if $a is tied or overloaded, what order should the tie/overload stuff be called in?	[reply] [d/l]
