All good responses so far. I'll agree, in this example, I can't see a reason though.

Just to add, another useful instance is if you want to avoid a long nested "if/else" structure, eg, instead of:

if ($var eq 'one') { &subOne; } elsif ($var eq 'two') { &subTwo; } ... elsif ($var eq 'ten') { &subTen; } else { die "Invalid \$var"; }
use this instead
my %subs = ( one => \&subOne, two => \&subTwo, ... ten => \&subTen, ); if ( exists $subs{$var} ) { &{$subs{$var}}; } else { die "Invalid \$var"; }

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
