That's why I'm preferring the common-lisp syntax of :param value, or
its variant param: value.

Well, with the exception of function argument list, beginning with
( and ending with ) and where parameters are separated by ,. Maybe

SELECT foo(a, :c 5);
SELECT foo(a, c: 5);
Not so much new punctuation characters there, 1 out of 4.
