If I have a list like this one:
@list = qw( a b c d e f );
I can easily loop through each element with a simple
for loop like this:
for $el (@list) {
print "$el\n";
}
But suppose the elements in the loop are grouped two and two and that for each loop I want to get two elements. Something like this (I know the syntax is all wrong):
for $el1, $el2 (@list) {
print "$el1 - $el2\n";
}
I know there must be an easy way to do this (this being perl and all), but I can't figure it out. Anyone?
