By analogy, we could add a row:
Interpolates
No Yes
-- ---
@foo @foo[1]
%bar %bar{"a"}
$foo.bar $foo.bar()
The basic rule of thumb seems to be shaping up that anything more
complicated than a simple scalar variable must always end with something
bracketed. (And in the case of closure {...}, that's the whole thing.)
Hmm. That makes me wonder what the slice notation for "everything" is.
