Description

r-arrow builds in an environment which combines MSVC and clang, invalidating assumptions made in nameof<>() which is used to look up R6 class names. Specifically:

• MSVC prefixes "struct " or "class " to some type names, but this doesn't happen in clang+msvc
• clang+msvc renders the signature of a function taking no arguments as "(void)" instead of "()"
