Especially if you're inspired by S-expressions, I can't imagine any good
excuse to invent a new syntax when lisp already has a syntax for this
sort of thing.  If we need to use square brackets instead of round ones
for legacy (or other) reasons, that's fine, but I don't at all see why
it makes sense to choose a syntax where of all things there's no outer
set of parens around the entire
function/macro/template/whatever-you-call-this-thing.  Why not do this:

  [def foo[a] [a]]

?
