It was because the transparent proxy for calling static methods was
constructed from an interface, whereas the transparent proxy for
instance methods was constructed from the type of a class. So a
'SmokeMethod' Attribute needed to be added to the method declaration
for the interface of static method calls with these flags:

| AttributeTargets.Method
| AttributeTargets.InterfaceFor example:

The interface for constructing a transparent proxy for static method
calls needed to be annotated like this:

interface IQWidgetProxy {
    [SmokeMethod("tr", "(const char*, const char*)", "$$")]
    string Tr(string s, string c);
