in reply to Ruby vs Perl vs LISP; the killer feature lacking in Ruby

You don't mention it explicitly, but my impression is that you've been using Lisp and Perl for a lot longer than you've been using Ruby. If that is indeed the case, then it should not be especially surprising that when using Lisp and Perl you don't need to devote as much time to thinking about the model, syntax, APIs and idioms of the programming language than you do with Ruby, a language you have less experience with.

    I find that using LISP interrupts the flow of my thought processes much more than Perl or Ruby. Probably because I've done similar amounts of stuff in Ruby and Perl, and don't really know any LISP. Then again, it could be the all caps vs. normally capitalized names...

[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.
