   The problem with "untyped" expressions is that they are inherently
   ambiguous. If I'm writing about  semigroups and regular languages I must
   tell you when a*b is concatenation and when it is semigroup addition.
   Figuring this out from the context alone is difficult for most people.

This sounds more like overuse of operator overloading rather than anything
having to do with static vs. dynamic typing.  This problem could occur just as
easily in C++ as in CLOS.  If you never want to mix the two types then 
renaming the operators will remove all confusion.  If you do want to mix the
two types then the problem is the same whether you are using a dynamically
typed language or a statically typed sortof-dynamic-typing-through-subclassing-
and-virtual-functions language.
