Is there not also a problem with boost::lambda using _n placeholders ? 
Or is this a non-problem because the end-user is expected to use either 
boost::lambda or boost::phoenix, but never both at the same time,  since 
the latter is supposed to supercede the former ?

I have always felt that none of these placeholders should have been 
lifted into the global namespace by default. An end-user can always do 
this for himself if he desires and then the often reported conflict with 
these placeholders is solved by not moving more than one of them into 
the global namespace.

As for unification of these placeholders, if it can be done and made 
interoperable I think it is a worthy thing to do.
