This is a slippery slope. If you have various output options, then you also
would want to cleanly input those same outputs. There are already some output
options for date/time, to accomodate the world-wide variations in same. Having
a fully-general input/output capability for all data types which bypasses
functions and views seems to be ignoring the power of those existing
mechanisms...
otoh, we _do_ have to figure out how to implement the decimal/numeric type
someday, so dive in :)
