I don't know what exactly you're after, but you can use
foreach on a whatever-they're-called-now tuple (there's been a
discussion about the name which I haven't followed; I mean the
kind you get from a TemplateTupleParameter):
void f1() {}
void f2() {}
void callThemAll(functions ...)()

You're right.

You can use a function lambda:

Note, I had to put (real a) even though I would have expected
"a => cos(a)" to work.

Yes, though you need to use an entirely different approach for
closures: make a struct.
Remember that delegates can come from local variable use or a
`this` object being used and work the same way to the outside

By the way i'd be interested to see the runtime function that
