my @array = grep (/\Q$file_name\E/i, keys %pathname_versions);

That's the right thing.

[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.
[Discipulus]: my ($need,$opta,$optb ) = @_; .. if $opta..
[shmem]: all else leads to trouble, even if the third argument depends on the existence of the second. That may become brittle.
[Discipulus]: but if have case like subname(15,undef,3 ) maybe bettere named parameters
[Lady_Aleena]: I don't want to have to do: alpha_menu($hash, undef, $type);
[Lady_Aleena]: Or what Discipulus said.
