I've heard similar questions among the aldor community.  IIUC aldor is a
second cut at a mathematical programming language.  Its original use was
to provide the underpinning to the Axiom family of CAS.  They are
exploring the use of aldor outside of CAS support, however.  The
language is strongly typed, and the "domains" include things like Ring
and Field.
