in thread iterating hash keys?

No, but they are being marked as word boundaries, and so they pass the regex I gave before. For the situation you've described, the only obvious solution I can see is to traverse the key list from long to short as I've shown in Re^5: using hashes. Things get messy with replacement lists when your keys are not independent.


#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.

[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.
[Discipulus]: my ($need,$opta,$optb ) = @_; .. if $opta..
