Coercion from strings to numbers are considered a bad thing, and can
(should?) be removed in future versions. It did not seem worth to extend
to the new integer stuff something already outdate. (Ideally it should
raise an error, but that would create all sorts of incompatibilities.)
In other words, it is unnatural, but the whole coercion stuff is unnatural.
