I'm interested to know what the situations are where you want the
behaviour of atoi().

Personally, I consider the int() function too permissive because of
its behaviour in truncating non-integer numeric types. But then that's
because I'm always paranoid that the values of my precious numbers are
being changed without my knowledge. From my vantage point I really
can't see why the ambiguous behaviour of atoi() would actually be
desired by anyone (unless they were stuck using a language that made
string manipulation generally a bit awkward).
