The latter:  having 'version=A '  inside the function.
Currently we can only set version=A at module scope, not function scope. I
don't understand the rationale for this limitation.
Likewise with 'version(A):' which is allowed at module scope but not
function scope, ; this would be  especially useful with 'version(none):'.
