yes, this also helped me identify some issues, but as far as I know all
of them implement e.g. ":=" and "?=" and macros in target rules. Of
course one might say that it's enough to cover multiple
implementations, but given there's often no reason to use extensions,
something like Mattias proposed would really come in handy.

With best regards
