same here, +1

I was wondering if creating a constant for it would be, stylistically
speaking, a cleaner solution. For instance:

#define EXTENSION_SYSTEM_MACRO  "$system"

I realize that it's used only inside get_extension_control_directories()
but since it is even mentioned in the docs, I guess it wouldn't be a bad
idea.

Thanks!

Best, Jim
