Please Pavel, 
you are very welcome if you want to do that.

But honestly, this is not a top priority of the core developper list
for the moment, so don't expect that this will be 
implemented in near future by one of us...

So, but sometiles, I prefer to disappoint you 
right away, rather than letting you hope for
something that has only little chance to happen
in a decent time distance.

Explicit typecasting will be your only way out of this incompatibility 
for now and for quite a while.....
