I'm OK with making the printed representation similar to the
source code.  But when that is in turn used to motivate changes to the
source code, I think it's gone too far.
It's hard enough to design good source syntax without such constraints.

Also, I think it's good if the source syntax is a bit different from the
function value syntax: we want the two to be *similar* so the function
value feels familiar and can intuitively be understood, but we also want
to make it clear that we're looking at something
fundamentally different.

That's why I'd favor a representation of the form #[...] or #<...> or ...
