Some (println) weirdness (board is a vector to vectors):
(println (board 0))
(println (board 1))
(println (board 2))
(println (board 3))
(println (board 4))
(println (board 5))
(println (board 6))
(println (board 7))
Works as I would expect, printing to the console.
However:
(for [row board]
(println row))
Doesn't: the output from println is part of the result of evaluating the
for (along with a slew of nils).
([:empty :empty :empty :empty :empty :empty :empty :empty]
[:empty :empty :empty :empty :empty :empty :empty :empty]
[:empty :empty :empty :empty :empty :empty :empty :empty]
[:empty :empty :empty :white :black :empty :empty :empty]
[:empty :empty :empty :black :white :empty :empty :empty]
[:empty :empty :empty :empty :empty :empty :empty :empty]
[:empty :empty :empty :empty :empty :empty :empty :empty]
[:empty :empty :empty :empty :empty :empty :empty :empty]
nil nil nil nil nil nil nil nil)
Any idea why there is any difference at all between the two? The only thing
I can think of is for's lazy evaluation but I don't see how.
