Makefiles allow custom shells. So with a small wrapper script we can use D in makefile. Here's my proof of concept: https://gist.github.com/Superstar64/8b896312ebe1a6e6240b1cba8aed2488.

If you define
SHELL = rdmd
you might not need any wrapper script.

Since newlines in make mean new execution, you will find it pretty hard to write a recipe that will be both usable and readable. This is, of course, assuming you overcome the fact that rdmd does not accept the program as a "-c" argument.

IIRC there is an option in gmake that allows one to run all commands within the same shell. https://www.gnu.org/software/make/manual/html_node/One-Shell.html. Anyway, it seems such usage of rdmd would be quite extreme. -- Andrei

Was not aware of this. Thanks!

Too bad it's an all or nothing thing. It would, otherwise, have been very useful to me in various make files I've written in the past.
