Having just once again suffered through the dimly remembered pain of learning about Jekyll, Liquid, and hash arrays, I am recording it here to save myself the next time I go for a few years between dealing with it. Official documentation does not say this (enough?), I guess because they think, "They can't, so let's not bother talking about it." This leaves the experienced programmer new to Liquid going "I should be able to do this, why can't I just assign myHash = { one: 1, two: 2 } or ["one" => "1", "two" => "2"] or some combination of braces and quotes or other punctuation? Do I just have the syntax wrong???"
