Perl Barracks, for sure; or to stay in that environment "The Perl Regiment".

D'Oh! I disagree but I'm seriously in difficulty because your arguments are all so good++ and I could hardly counter them. Though I suppose that a comment similar to that in response to the brothel suggestion may apply: $Larry would probably not approve of the association between Perl and something military...

A counter argument: how 'bout free form? Something that can be brought so forth in Perl up to that incredible anarchic mess that obfu and golf can be. Well, I guess one may provide as a counter-counter-argument an interpretation in terms of mimetism and blitz operations...

Last, you may ask me why I despise the military option while I cherish the dojo one, when "martial arts", literally, mean "arts of war". Well, of course it's all a matter of personal tastes and opinions: but once you accept this POV, it must be said that the term dojo typically applied to martial arts with a do in their name, thus shifting the main point of interest from the pure development of technical skills to that of a more general "Way" - although it has been generalized to other ones. I don't know if that could be the case with Perl, or even if it would be desirable... but I for one like the idea!
