foreach is dead, long live for.
I would myself use "for" for the C-style loops
And this is why. As long as people think "well, I have foreach which
is for iterating and for which is for C-style loops" they will
continue to write C-style loops. C-style loops are bad. They are
there for backwards compatibility. I can't think of a single for loop
that isn't better written as a range based for loop or while loop. For
instance
standard range based loop
for (my $i = 0; $i < 10; $i++) {}
for my $i (0 .. 9) {}
How about:
for ( my $i = 0; $i < 10; $i += 3 ) {}
foreach my $i ( ? .. ? ) {}
And
for (my $elem = $doc->firstChild; $elem; $elem = $elem->nextSibling) {
:
}
