Get A Compiler Warning For Functions Returning Value Types, Without Return Statement

I've just been burned again by the fact that there is no compiler warning when you fail to return a result in a Function that returns a Value type. I wrote the function:

Public Function CompareTo(ByVal other As MessageIndex) As Integer Implements System.IComparable(Of MessageIndex).CompareTo
Me._messageIndex.CompareTo(other._messageIndex)
End Function

which performs the CompareTo Function for two integers, then throws the result away and returns 0, because I forgot to either assign a value to CompareTo, or use Return, and that isn't flagged by the compiler because it's valid VB for a Value type.

I happen never to use "FunctionName = ReturnValue" because it hides information from maintenance programmers and also because I think it's insane .

Is there any way I can get the compiler to issue a warning whenever my Functions are missing a Return, whether it's a Value type or not?
