Unfortunately for Ben, Ruby also falls into the "truly horrible idea"
category. Ruby variables are _not_ typed, but take on the type of
whatever they happen to reference at the time. Similarly, the majority 
of operators have no semantic meaning to Ruby, as they are simply
method calls. This is the same as the Smalltalk and (in my limited
understanding) the Javascript model.

This lack of constraint is one of the defining features of the
language.
