It may be a bad idea to encourage code with substantial nested
functions in Erlang. When you say "X = foo()", its meaning depends on
the context -- whether X is already bound. The more context the
expression is nested within, the more this would matter. We're used to
lots of nesting in e.g. Scheme or Haskell, but in those languages the
scope rules are different.
