By someone who clearly cannot count to 4?

OP here. Sorry for the code-golfy post on HN. But, some clarifications:

1. Yes, it is O(n!) - it says so in the description but not on the title of the post on HN.

2. It is 4 lines of code for `nQueen` function. I did not include the printing code in the line count.

3. And no, I did not cheat by using semicolons in same lines - these are 4 legit lines IMO. You can put the `&` clause in 1 line to reduce it further.
