it makes sense to not throw now that I think about it, when using "_"
instead of "a"
I'm also thinking of cases like:
=> (let [a 1]
(let [b 2 a 3]
(println a b)))
3 2
nil
is there something that would let me know I'm overwriting "a" ? I figure if
something like this would slip by would be tough to track down
