# Symbol to Proc is a mutha' fucking dirty hack. It brings the indirection
# that we hated from Pearl to Ruby. How it made it into core I don't know.
# Anyway, rather than bitch and moan too much, here is an alternative method
# which is much more expressive and has the same number of characters. The
# name pick comes from Rebol, though it functions more like select there.
