Just realized I used "f" twice, make the outer one something else. On Tue, Oct 4, 2011 at 5:27 AM, Sebastien Zany < sebastien@chaoticresearch.com> wrote:
What would be the idiomatic way to write a function which expands to the following?
f n m = do { x1 <- m; guard (f [x1]); x2 <- m; guard (f [x1, x2]); . . . xn <- m; guard (f [x1,x2,...,xn]); }
What I'm trying to do is generate a list of lists of length n with some property (checked by f) efficiently.
