My only concern is with hashes, since they come in no particular order
unless sorted, there probably would not be any use to iterate over the
values of more than one hash? At least I can't think of any use. But it
would be nice to iterate over one hash, like so...
for (%my_hash)
{ ... }
But this will be flattened, so I would think
for my($key, $val)(%my_hash)
{ ... }
Would be a great convenience. $key and $val being aliased accordingly.

]- yes ALIASING will be better, instead of copyng values into $el,$el2
scalars.... just one point I placed around them "(" ")", so that the
arrays
would be flattened :") ... but now as u told it will be beter they to be
aliases.. so may be this is the right one :
for my ($e1,$2,e3...,$eX) ( @a1, @a2, @a3, .. @aX) {
.....blah...
}
and later on the first iteration $el's are aliased to the zero elements
of
arrays (if the $el's are more than @a's then the latest $el's are not
aliased/probably undef'ed/, if @a's are more then all $el's are occuped
and
on the next iteration they doesn't start to be aliesed again from the
@a1
but from the next @a's !!).
If we have Scalars in the list, then they behave as array with one
element
(just got aliesed every time).
If we have Hashes then VALUES get aliased... if someone wants keys it
should
write explictly keys %hash (temporarily has to be created scalars may
be),
the same with each.
just one possible solution.. may be there is many things i've not seen..
And then what about this :")
for my ( $e1, @els,$el3) ( @a1, 5..10, @a2,%h1, $x .. @aX) {
.....blah...
};
:"))) There is endless ways to do it : TIEWTDI
