--- Comment #7 from Esme Povirk madewokherd@gmail.com --- If I comment out the calls to check_call_signature, it gets further, now failing to convert "&H0" to in integer in Microsoft.VisualBasic.CompilerServices.IntegerType.FromString.
The &H format denotes a hex literal in Visual Basic, so it's entirely reasonable to expect this to work.
