Printing pointer causes error

[jumerckx]

Following code throws an error:

using CassetteOverlay
@MethodTable MyTable
mypass = @overlaypass MyTable
mypass() do
    print(Ptr{Nothing}(0))
end

ERROR: type DataType has no field body

This seems similar to https://github.com/JuliaDebug/CassetteOverlay.jl/issues/33#issuecomment-1562982637. When I define:

@inline (::typeof(mypass))(::typeof(Base.typename), @nospecialize args...) = 
    Base.typename(args...)

after the pass has been created, it works. Is there a better fix?
