Perhaps some future version of the compiler could warn against unused
variable bindings?  This is a feature that is in Perl, but I find it
somewhat annoying to me there (as it does not match my
imperative/procedural programming style, where mutable variables can be
updated arbitrarily anyway.)

But in Erlang is would actually make a lot more sense and I think I
would like it a lot.
