#1488: vectorize(): could the dtype of the output array be the "smallest possible
dtype"?

It would be nice if vectorize()'d functions returned arrays with the
"smallest possible dtype". Maybe such a feature could be added as a flag
in vectorize's arguments?
Thus, the result of a vectorized function would be more robust; currently,
if the first call to the vectorized function returned an array of
integers, all its subsequent calls return integers even when the user
really expects floats. This problem might be hard to detect, in a long
and complicated matrix calculation.
This could be one solution to the ticket in
