Journal eglamkowski's Journal: neat 3

Journal by eglamkowski on Monday February 13, 2006 @11:09AM

I don't write perl scripts very often, and when I do they usually aren't anything fancy. So this may seem quaint or elementary to some of you, but I was quite delighted to discover I could do this:

push(@{ $hash{"KEYNAME"} }, "value1"); push(@{ $hash{"KEYNAME"} }, "value2"); push(@{ $hash{"KEYNAME"} }, "value3"); push(@{ $hash{"KEYNAME"} }, "value4"); foreach $string (keys %hash) { print "$string: @{$hash{$string}}\n"; }

That is to say, a hash where the "value" part of the key-value pair was an array instead of a scalar.

Neat.

Same code - faster:

push @{ $hash{"KEYNAME"} }, "value1", "value2", "value3", "value4";

  I wish I had more reason to write in perl. It's a fascinating language with lots of hacker potential.
  Perl was actually the first langauge I learned. I quickly moved on to C and then C++, but I still like Perl best.

Yet after looking at that and figuring out what it does, I agree with your summary.
