Claude Brisson commented on VELOCITY-904:
-----------------------------------------
2.x macros are more like functions than macros. Especially, the current
documentation is wrong on this subject and needs to be updated. It's not that
the `$test` argument shadows `$test.name`, it's that `$test.name` is evaluated
beforehand.
> Add a flag for better backward compatibility with null macro arguments
