Gotcha! I guess it is too late over here to read documentation. :)

But I still wonder how much of a penalty there is.

    Its apparently the same penalty incurred on a per-regex basis by using capturing. While working with Metacode::Reader I was able to get some very nice speedups by removing everything that copies data around. So instead of /H=(\d+)$/ I had substr $_, $-[0] + 2, $+[0] - $-[0] - 3. This is much less clear and not nice to read. In my case I was writing a high volumn database filter and the obfuscation was ok. I don't advocate at all taking this sort of step outside of really critical code that Devel::DProf has already highlighted as being slow.

[1nickt]: But the bands are even louder! I saw Spearhead (Michael Franti) at an outdoor show and had to walk a mile away to not feel pain in my chest! Babies were crying ... I asked the sound engineer why it was necessary to have the bass so loud and he laughed...
[Discipulus]: but the best i attended live was Mano Negra Patchanka at Forte Prenestino .. in 1990
[Corion]: Hmmm - Mano Negra or at least Manu Chao seem to put on a good live show. At least the one live CD I have from Manu Chao sounds good ;)
Discipulus feels the same jealousity of the johngg's daughter
[1nickt]: choroba I agree
[choroba]: Playing in a punk rock band for 20 years... my hearing is quite bad
[Corion]: I still have hopes to turn my godson and his two siblings into a punk band ;)
[Corion]: Their older sister just started piano but has been interested in drumming, which she should be able to start with 8 years or so)
[Discipulus]: ah was Kink of Bongo 1992..
[1nickt]: choroba name of band? youtube link? MySpace link?
