It's not completely useless: "int foobar(int delegate(int) f) { }" allows
you to choose what delegate to send at run-time. "int foobar3(alias f)()
{ }" doesn't. (Although, I suppose you might be able to work around that
moving the run-time selection from the caller of foobar3 to the delegate
passed into "int foobar3(alias f)() { }". Not sure if there are cases where
that would be awkward to do.)
In fact you can select the alias at runtime, which is quite a trick.
