i was confused by the meaning of coll, too . . .even at a more basic level
of not knowing that it meant collection. I even thought at first I was
seeing "col1" or that the second lower('L') was a capitol(i). I read it as,
"column one" in my head.
Is it accurate to call it "some-seq" or something? I would think "sequable"
would be even better but it puts the responsibility on the function to call
seq on java arrays, which means there's an extra if-check all the time (if I
understand the definition of the word, "sequable").
