I havent tried for other datatypes...
e.g. int -> decimal, double -> decimal, etc.

+A user-defined implicit conversion from type S to type T is processed
+Find the set of types, D, from which user-defined conversion
+operators will be considered....
+Find the set of applicable user-defined conversion operators, U. This
+set consists of the user-defined implicit conversion operators
+declared by the classes or structs in D that convert from a type
+encompassing S to a type encompassed by T.
+Find the most specific source type, SX, of the operators in U: ...
+Find the most specific target type, TX, of the operators in U: ...
+[if U has > 1 op], the user-defined conversion is applied:
+If S is not SX, then a standard implicit conversion from S to SX is
+The most specific user-defined conversion operator is invoked to
+convert from SX to TX.
+If TX is not T, then a standard implicit conversion from TX to T is
+So, we are missing the "if TX is not T" clause. I think the "S is not
+SX" is already covered because the source always has to be either S
+or a parent class of S. I am pretty sure we already cover this
+situation. However, TX -> T could be *any* implict conversion.
