bindings list and infer/validate the type of this expression or its subexpressions
where possible

typeCheck(Type expected) |
ensure that all type references in the expression and its component expressions
can be resolved, that the type of the expression is well-defined and that it is
compatible with the type expected in the context in which it occurs.

helper
- an execution context associated with the rule whcih contains a map of
current bindings for rule variables and another map of their declared types both of which
are indexed by varoable name. This includes entries for the helper (name "-1"), the
recipient if the trigger method is not static (name "0") and the trigger method arguments
(names "1", ...)ExecuteException
