Indeed. [IMHO, it would have been a less painful to not try anything in
the way of "smooth transition" where such radical changes (checked vs
unchecked) are concerned.]

Also, if I may insist, we had somewhat agreed about a freeze concerning the
big changes in "trunk" (targetting a release of 3.0 around spring!).
Even if the "map" idea can be useful, it can be implemented after 3.0, in a
backward-compatible way.

Then further down in time (i.e. towards 4.0), when we can have some actual
experience with the design as it is now, we will, if necessary, make the
incompatible changes (like removing exceptions).
