	* pending.cs (PendingImplementation): Rework so we can keep track
	of interface types all the time, and flag those which were
	implemented by parents as optional.

	* expression.cs (Binary.ResolveOperator): Use
	String.Concat(string,string,string) or
	String.Concat(string,string,string,string) when possible.

	* typemanager: More helper methods.
