Based on your code sample, might I suggest a hash lookup table, eg:

# Untested my @filesize_names = qw(kilobyte megabyte gigabyte terabyte petabyte e +xabyte zettabyte yottabyte); my %short_sizes = map { m/^(\w)/; $1 . 'b' => $_ } @filesize_names; my $word = 'kb'; if ( exists $short_sizes{lc $word} ) { say $short_sizes{lc $word}; }

[Lady_Aleena]: Right now, I'm trying to decide whether I want to rewrite how variables are entered in the sub I'm working on.
[shmem]: wait, what? you want that person to read the documentation for you?
[Lady_Aleena]: I might have to go with options instead of a straight list.
[Discipulus]: if more than 3 go for named variables LA
[Lady_Aleena]: Discipulus, it is at 2 now, but with what I am thinking about, it could go to 3. However, only 1 is needed. The second and third are optional.
[shmem]: straight list or named parameters - that depends on whether (and how many) optional arguments you have
[Discipulus]: if so a plain list is ok, imho
[Lady_Aleena]: shmem, I already have the plugin installed, just not active.
[shmem]: if you have 1 optional argument, place that at the end of the list. If you have more, go for named parameters.
[Lady_Aleena]: 1 manditory, 2 optional.
