+Summary: test-53 is invalid
+
+Test 53 for mcs is invalid.
+
+It involves a statement:
+
+		using (NoIDispose a = new NoIDispose ()){
+		}
+
+Where NoIDispose is not idisposable, but has an implicit coversion to a
+class that is.
+
+THe spec says:
+1 If the form of resource-acquisition is local-variable-declaration then
+the type of the local-variable-declaration must be System.IDisposable or a
+type that can be implicitly converted to System.IDisposable. 2 If the form
+of resource-acquisition is expression then this expression must be
+System.IDisposable or a type that can be implicitly converted to
+System.IDisposable. 
+
+Clause 2 does not allow multiple implicit conversions to be used (this
+could very well cause the compiler to go through a tedious process to
+resolve a class). We need not worry about a direct implict coversion to
+IDisposable, since that is not allowed.
