There is not for either for or foreach. This is generally not a problem
in for as programmers generally use an interation variable as a for's
termination condition. i.e. :
for (my $i = 0; $i < length (@array); $i++)
which is how you can loop over an array and have an interation variable.
It is a problem in foreach like in your example. (you meant to write
foreach in your example and not for, right?) This is why they are
considering (or maybe have come to a final descion since I last looked)
adding a variable to do this. Damian seemed to be a big supporter of
this. It'll very likely be in perl6.
