You could change the ellipsis to Integer. :)
Or no-check could bind ellipsis to some type. This would be useful for sketching types out in no-check and then refining them to actual types in TR.

As a semi-random data point, I sometime use my no-check language (which is built on top of TR's) to show how things work in class without getting all the types right (or when there's some problem with the types). In these cases I sometime use bogus type declarations like "(All (A B) ...)", which IIUC wouldn't work anymore. It's just technically simpler and clearer to still use `:' instead of going back to comments. (But it's obviously a weak point.) -- ((lambda (x) (x x)) (lambda (x) (x x))) Eli Barzilay: http://barzilay.org/ Maze is Life! _________________________ Racket Developers list: http://lists.racket-lang.org/dev _________________________ Racket Developers list: http://lists.racket-lang.org/dev
