Very nice idea. Splice literal to go with the slice literal. It can't be a "return", but I think we can do it with the JS comma operator.
(a.splice.apply(a,[1,3].concat([1,2,3])), a)
from coffeescript.
Sounds good.

Splice literals are now on master. Your first example:
a[5..8] = [1,2,3]
Compiles to:
a.splice.apply(a, [5, 8 - 5 + 1].concat([1, 2, 3]));
You can use inclusive or exclusive ranges, as usual. We actually don't need to worry about the return value, because splices modify the array in place, and it's an AssignNode that's doing the compilation, suppressing the actual, y'know, assignment.
Closing the ticket.
