This is not a some magic beast coming out of functional languages. In
fact, it's pretty hard to find a language that can't do this sort of
thing, even older Fortrans let you pass functions.

Yes, but that's something completely different! It's not like you're
able to do (using your notation):
set(&tmp &install)
set(&install &add_executable)
set(&add_executable &tmp)
In C/C++ and to various extent in Fortran (depending on the version)
you can pass around "function pointers". This is _not_ a function.
There's no way of doing that in C/C++ or Fortran (that is, without
using ugly preprocessor magic).
