To be more specific Python Virtual Machine doesn't do implicit
conversions. However any class including builtin ones can
convert any input argument to any other type. From the
outer point of view (e.g. user of int class) it's implicit conversion,
but from inner point of view (e.g. int class) there is no implicit
conversions of input arguments so the int class has to explicitly
convert them.
