I personally believe that that's the least of the problems. We're talking about poetry here. There are quite a lot of poems that do not use punctuation at all or use much sparser punctuation than prose. Pauses are often suggested by line breaks and the like. I have some poems of my own: not Perl poems, since I don't like that as concept - for me a particularly well written piece of code is poetry! (As can be considered a mathematical formula, in some respects, because it aims at expressing the maximum significance in the least significant - I hope to have got the linguistic terms right, they're missing from my physical IT-EN dictionary and I couldn't find them online...) Now, some of them have more or less "regular" punctuation, some have somewhat "alternative" punctuation, and some do not have it at all. Of course, this is not the proof of anything: I'm not a poet. Indeed, my whole production counts eleven poems in about thirteen years!! (Those are the ones I've valued to be worth keeping...)
