depends on value of the first two elements of the list, f1, f2 and f3 will return three different values. So is it safe ?
If "f xs" always returns the same value for a given xs, then it's safe. Doesn't look like that's the case here, though, since depending on the GHC runtime scheduler f1 may finish first in one case, and then the next time f2 may finish first, meaning that f xs will return two different results for the same xs. So that's not safe, and thus it should be in the IO monad. /S -- Sebastian Sylvan +46(0)736-818655 UIN: 44640862
