Despite the glib comment, the idea as presented doesn't work because it
mixes statement and expression semantics (the inner 'return' is at best
unpleasant). Also, the naming is off -- 'def' defines some variable
name. In Lua, the 'def' is called 'function' which doesn't imply a
variable assignment.
