Have you, by chance, put this up at a Ruby-focused site? I'd be interested to read comments on it from entrenched Ruby folks.
I would be too... my (brief) encounters with the Ruby community so far have only turned up rampant fanboi-ism. Actually, it's one of the things that's put me off pursuing Ruby further. I'm sure it's just a case of bad luck, altho I do suspect that the average Rubyite is a bit more defensive than the averager Perler (I think Perl coders are just used to abuse nowadays). Would be interesting to compare the quality of responses to a post on a Ruby site to those on this site (which are all excellent so far).
