I am also curious about how to use Environments for this kind of thing.
Right now I am experimenting with an alternative implementation of DateAndTime,
and I'm using the good old fashioned approach of giving it a different
name, in this case LXDateAndTime. Assuming that I get it working, I will
want to be able to replace the current DateAndTime with the new one,
but keep the original one working until it is no longer needed. Of course,
DateAndTime is used for source code time stamps, so there is a period
of time when both implementations have to be in the image. It would
be nice if I could do this with the new implementation being named
DateAndTime (not LXDateAndTime).
