a little syntactic sugar with an improvised in operator and given/when has no better readability anymore.

use strict; use warnings; sub in { for my $val (@_) { return 1 if $_ eq $val; } return; } sub test1 { my ($var) = @_; my $i; for ($var) { if ( in 1 ) { $i = "One" } elsif ( in 2 ) { $i = "Two" } elsif ( in 3,4,5 ) { $i = "Three, Four or Five" } else { $i = "Other" } } print "$var is $i\n"; } sub test2 { my ($var) = @_; my $i; for ($var) { if ( in 1 ) { $i = "One" ;next} if ( in 2 ) { $i = "Two" ;next} if ( in 3,4,5 ) { $i = "Three, Four or Five" ;next} $i = "Other" } print "$var is $i\n"; } test1($_) for 1..6; test2($_) for 1..6;

) though I think it's still faster, it might be able to automatically optimize to hash-lookups

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

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
