# Motivation for this madness: I often find that simply a function is
# a nice interface objects. However, often later on a need arises that
# we need also something else in a return value / argument, which currently
# calls for refactoring of every call site. In Python this can be hacked
# around using __call__. This would be a way to hack around it in LiveScript.
#
# And anyway I think having separate "classes" and "objects" is a bit stupid
# historical artefact. KISS!
