Re^3: Iterating over verbatim hash reference

I have a slight preference for omitting variable names if I don't really need them.

If you are concerned about cluttering up a (possibly over-broad) scope with needless nonce variable names (not an entirely unreasonable concern, IMO), why not just enclose the sub-section of code in its own limited sub-scope?

>perl -wMstrict -le
"{ my %h = qw(a 1  b 2  c 3);
   while (my ($k, $v) = each %h) {
     print qq{$k -> $v};
     }
   }
"
c -> 3
a -> 1
b -> 2

why not just enclose the sub-section of code in its own limited scope? Simply for reason of aesthetics ;-) As was already pointed out, there are many ways to skin the cat. I was just wondering whether Perl language really dictates us here to introduce a variable name, since in all other cases I can think of, an expression which is only needed once, doesn't need to be named. Having found this case where I could not do without introducing a variable, I considered it more likey that I was just missing some feature of Perl... -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l]
