[erlang-questions] Good one-liners?

[Christian S]

Hi, I keep seeing these perl programmers in teeshirts with one-liners
printed on them. It made me think about what erlang one-liners I would
want on a teeshirt.

I mean, something in erlang that gives you the same fuzzy feeling as
math people get over eulers identity: e^{j*pi} + 1 = 0

Or something world domination-ish:
  [enlight(P) || P <- Programmers, false == knows_erlang(P)]

PS
Why not have a parallel list-comprehension syntax? What pmap is to map.
