Make can't decide whether it's a dependency graph or a macro language. That leads to weird semantics like this.

That's why I like ASDF3: it manages dependency graphs with a superlative macro language not of its own design.
Make is a dependency graph with macroes for not having to repeat, copy-and-paste, and hard-code stuff.
You have rough corners in every language. Make is actually quite good
(meaning: easy to read, without much gymnastics) in its typical use case of
compiling a software project. The post was written specifically to explore
one of these rough corners everything has.

Reading it may be easy, but every time I've tried to use make (i.e. write a Makefile that does what I want) I've found it to be composed almost entirely of rough corners.

Yes, and I've purchased and read books, and I've read online resources. Granted, none of this has been within the last several years, so if there have been major changes in that span I've missed them.
But thanks for the charitable question!
Whoa. This is NOT a rough corner. It is a fundamental part of the language. Deferred variables are akin to functions in other languages, while immediate ones are more like variables in other languages.
