Classic recursive-descent parser? An expression is a sequence of terms, 
a term is a sequence of factors, one of the possibilities for a factor 
is a parenthesised expression.

However, there's probably still a way round that in a unit, by moving 
the first mention of one of those into the definition part. Or similarly 
you might be able to avoid it by using object definitions.
