Breaking backwards compatibility would be nuts, of course. Just wonder if
the alternative notation could *also* be supported.

what should the reader do when it encounters "foo:"?
"Symbols beginning or ending with ':' are reserved by Clojure. A symbol can
contain one or more non-repeating ':'s."
note that foo: is not a symbol.
once you get the hang of clojure you will drop the idea that {foo: 1} is
more expressive than {:foo 1}. It's kinda like getting over the
parentheses.

Looking at that it seems at least plausible.
