Null input throws null ref, should go to Else clause

[becdetat]

Passing a null in as the match value without a predicate condition matching against null currently throws a NullReferenceException inside Simplicity:

string name = null;

name.Match()
    .With("ben", "it me!")
    .Else("unknown")
    .Do()
    .Dump();

This should return "unknown".

Matching against (string)null also throws a NullReferenceException. This clause should match (string)null but it doesn't:

.With((string)null, "match on null")

Any progress on this?
