I think I'd hesitate before calling it a "feature", if that's what you mean
by 'sense'. :)
I admit my case was pretty marginal (int's as hash keys) but you've shown
that it's a general feature of Perl with your $a+=1 example. Using a float
as an array index is fairly common practice <g> so the Perl Porters probably
stuck in the auto-truncate rule in the compiler? I can't see doing this for
hash keys though... too wierd. I think I'm learning too much about perl's
internals (I'd rather be playing with Markov chains...)
So for a weak-typed language like Perl maybe it is a 'feature'. I assumed
arithmetic type rules were like C's.
Thanks for the tip on Devel.pm!
