I think "cause" is too strong a word here. Actually mutual
recursion is often a very good thing. The cause of the stack
overflow is still bug in implementation - not necessarily a
criticism of the design. In fact, I think that if we can find
the right tools for dealing with mutual recursion in Axiom,
this could represent a major advantage of Axiom for the direct
representation of mathematical concepts over all other computer
algebra systems.
