Hmmm. Didn't think about that. That would be a nice way, that way you can
manipulate it's behaviour depending with how many aliases you provide.
for my $el1, $el2 ( (@foo, @bar) ) {
print "$el\n"
}
$el1 and $el2 would of course be aliases, right?
But one though might be, what happens if this is written...
for my $el1, $el2 ( (@foo, @bar, @arr) ) {
print "$el\n"
}
Does this bahave in the same way as the first one, but we just don't set
@arr elements, since the user forgot to provide a third alias, or should
this croak at compile time?

]- Yes ... and one more option :
for my $el1, $el2 ( @foo, @bar ) {
print "$el1 : $el2\n"
}
$el1 will get values from @foo and $el2 from @bar, but the following :
for my $el ( @foo, @bar ) {
print "$el\n"
}
will print :
$foo[0]
$bar[0]
$foo[1]
$bar[1]
if people like the other way they can write :
for my $el ( (@foo, @bar) ) {
print "$el\n"
}
will print :
$foo[0]
$foo[1]
...$foo[x]
$bar[0]
$bar[1]
....
is this correct , but now I'm looking at these too...
http://dev.perl.org/rfc/90.pod
http://dev.perl.org/rfc/91.pod
http://dev.perl.org/rfc/148.pod
so may be what must be the order of passing the arguments and other
stuff
should be done via these proposed functions.
PS. I was thinking of that before, what if we have something let's call
it
'transform' for transformation of any structure to other structure.. but
as
i thought it should combine in some way the features of
switch,if-else,for/foeach, do, while, array/hash-slices, assignment
....etc.... .... oooops I'm talking about DWIM operator..... anyway...
is it
possible to really add such "dwim" function/operator that can be
modified on
the fly so that it suit all programmers tastes and don't make real
mess...")
... ok i say it :")))
