+Summary: Smarter implicit type conversions for constants?
+Trying to compile
+   ulong foo = 0L;
+results in
+   error CS0031: Constant value `0' cannot be converted to ulong
+I don't know what the C# spec says, but is that really the correct
+behavior?  Since the value is known at compile-time, we should be able to
+know whether or not the conversion from long to ulong is safe.  In this
+case, it would be nice if the compiler silently converted 0L to 0UL.
