Re: Are keys and vals guaranteed to return in the same order?

((symbol "whatever") 1 :a) evaluates to :a . How can this be?

An expression yielding an arbitrary symbol, used as a function, returns its second argument. ((symbol "whatever") 1 :a) => :a If it has one argument, it returns nil. ((symbol "whatever") 1) => nil It does not accept more than two arguments. ((symbol "whatever") 1 :a \z) => # And it does not a
