I must be missing something.  Can you give a specific example showing =
how the automatic use would conflict with something other than a root =
namespace?

Well, we frequently see things differently, which is what it is.=20

Myself, I like the explicit nature of it that allows seeing at a glance =
that it is Text without having to look up through a long PHP file to =
find the namespace statement.  But as my dad says, to each his own, I =
guess.

Besides, I think there may be some better solutions discussed on this =
thread besides our dueling qualification syntax.

Fair point.  But then treating built-ins differently than userland =
globals may be the way to go that has the least BC breakage over either =
of our two proposals here. =20

That said, having an automatic `use` would be nice for those who want to =
use it, even if it is not required.
