Interesting. So what you're actually against is the symbols. Okay. I
have a bit of a Scheme (rubs hands together with glee) for you. We can
thtandardithe on jutht one thymbol pair and uthe wordth for the retht.
And to make it clear that thith ith no function call, we'll put the
word *inthide* the parenthetheth.

(set 1 2 3)
(dict 1 2 3 4)   ; implicitly pairs up the arguments
(tuple 1 2)
(list 1 2 3 4)    ; This seems like a real good idea.
