Draft 2 of the spec for the Function class. Changelog near the
beginning; several small changes only.

Title: The class "Function"
The class Function
NAME: "The class 'Function'"
FILE: spec/library/Function.html
CATEGORY:
Why doesn't Function have something like apply that does the same as
in a new expression, i.e. allocate-init-and-apply? To put it another
way: given arguments in an array, I want to write:
F.thisThing(args) and have it mean the same as new F(args[0], args[1],
... args[n-1])
Or is what happens
Hi Dustin,
Well it does, apparently it was called the splat operator, which (to
me) sounds a better than spread. I think it works like:-
var args = [12, true];
new C(...args);
function C( count, isSemiAnnual) {
}
- Maybe one of guys writing the specs can comment on that.
It can be hacked in
Neat! Thanks for the link.

I agree with Lars on this issue for exactly the same reasons as what he stated.

I think there are three points to be made here. The first is
that the Function constructor provides functionality that
eval does not, namely, creating new functions that are closed
in the global environment only.
I promise not to drag out this discussion, since no one else seems to
be interested in it.

Symmetry with call and apply and a consequence

Suggestion: deprecate the Function constructor and static invoke().
Almost all of its uses are better handled by function expressions and,
in those cases where eval() in required,

There are valid use cases for new Function (...) and Function(...).
One that comes to mind is getting an attribute in DOM and make it into
an event handler. Yes, the Function constructor and meta::invoke can
be replaced by eval but
