BTW, some other advantage of such a representation --
* Having a name explicitly attached make it easier to see what it is,
even if you've never encountered such a thing before, the "#[" tells
you `hey it's connected with the lisp evaluator', and the
first-element name gives you strong clue to determine just exactly
what.
* It leaves a clear path for other special magic-callable objects.
E.g., another very useful notion is that of `reverse currying',
where the curried arguments get attached to the _end_ of the
argument list at call time, which could look like #[rcurry ...].
