You did ask. Someone not acquainted with ruby would think anything
when meeting those blocks. I could also say "x.each {pipe i pipe to
print i}", so " do, for each thing in x, a pipe to i, which is not
defined, and then a pipe to print i, which is still undefined". That,
thinking as a shell scripter. And yes, we're kidding, of course. At
least I am.

Seriously, that kind of stuff is not very appreciable to people who
don't even know what closures are, and if you're a fan of python, you
tend not to appreciate strange code like that. It requires heavy human
parsing, even if it's great.
