I think it lies in the history of programming. Traditionally for loops look
like this (when written in perl)
for($i=1; $i<=100; $i++){
print "$i\n";
}
while foreach loops look like this.
@array = qw(one two three);
foreach (@array) {
print "$_\n";
}
Even though you can do
for (@array) {
...
}
and
foreach($i=1; $i<=100; $i++){
...
}
it's not the "proper" syntax. Yes, it works and there is no difference other
than stylistic between them, but I think traditionalists would work up a
froth if perl only had the for or foreach command supported. And, as the
saying goes, TIMTOWDI, and it wouldn't be perl without that ;)
OTOH I could be completely wrong :)

if there's no difference, what's the point of having both? I can't see
how readable/maintanable would increase by adding functions with the
same name, it'd rather increase the confusion...
is there really no diff?
