In fact, this feature will be in the new API. If the "guess mode" is
active, then you will only have to set converters for columns that the
"guesser" doesn't get right.

For example:

    cu.typecasts = {"mycolumn": int}
    cu.execute("select a, b, c, func(a) as mycolumn from t1")

This will replace the "-- types" hack, which will only return if
there's real demand for it, for example if a ZOPE DA needs it.
