In D2 you should be able to use Phobos and Tango together, with the
caveat that Tango doesn't have a D2 release yet.

"    * Q: Does Tango support D 2.0 as represented by the DMD 2.0xx range
of releases?
    * A: No, not officially. A branch exists in Tango's SVN repository
with an early attempt, but D 2.0 is still considered too immature and
unstable for any full and official commitment to this end. Feel free to
contact us if you want to update the branch, though. "

The "D implementation" seems to remain roughly the same across the
compilers.  They all use the DMD frontend with some differing glue code
to turn the AST into something the backend can understand.

GDC seems to only support D1 at the moment.  For a while it was
abandoned, but has been revived recently.

LDC also supports D1 only at the moment.  It seems exception handling is
broken for Windows, thus making it impractical to compile general D
programs with LDC+Windows.  http://www.dsource.org/projects/ldc/ticket/123
Though this might not matter much for embedded stuff, unless you develop
on Windows.

I suspect D2 support will improve when D2 gets 'finished'.

I think Phobos might be more like boost/STL and Tango might be more like
Java's myriad out-of-the-box packages.

You seem to have a pretty good understanding of this stuff as far as I
can tell.  More than mine in most cases.

Hope this reply isn't too late.
