NUnit.Framework.Constraints.ResolvableConstraintExpression

ResolvableConstraintExpression is used to represent a compound constraint being constructed at a point where the last operator may either terminate the expression or may have additional qualifying constraints added to it. It is used, for example, for a Property element or for an Exception element, either of which may be optionally followed by constraints that apply to the property or exception.
