What I'm saying is that if you have a rule like this:

        foo:
                $(sleep 0.10) echo hi

The recipe is always expanded by make before it invokes the shell
command, so it would be make that runs the sleep operation, and make
that sleeps, before the shell is even started.

I don't think that would help the issue we're trying to solve (I really
can't see a valid use-case for $(sleep) to be honest).

But, maybe you were thinking of something different?
