I agree that lot's of stuff is going to break
and that the benefits are big.

If a merge is ever going to happen (and I hope it does)
it has do be done today rather than tomorrow.

Here is a three step plan:
- plan the basic design concept of a new std. namespace.
- rename the current std. to phobos.
- continue to populate std from Phobos and Tango.

The main point of debate would be the structure of the new std namespace.
It's hard to combine simplicity and small size have to be combined with 
the feature richness and speed of Tango.
