The problem with this conversion is that it is not reversible. Assuming
the obvious conversion, we have that false(b) -> "false(s)", but
"false(s)" -> true(b) (any string is non-false). So, we prefer not to
perform it implicitly.

(Actually, the conversion between numbers and strings is not completely
reversible, too: "0003" -> 3 -> "3". But most of the time it works as
we expect.)
