>
> Function resolution included a small condition to allow varchar and varbinary
> functions to be resolved for either incoming type. While it is valid to
> implicitly cast between these two, this early workaround creates a
> technically invalid expression tree that happens to work with the current
> code generation system. This however does create an issue for the interpreted
> expression evaluator. Removing the code simply causes an implicit cast to be
> added during materialization, this works for both generated code expression
> evaluation as well as the interpreter.
