Phobos differences?

[Alex Parrill via D.gnu]

I've noticed that GDC's version of Phobos is missing some 
features from DMD's. Is there a place to report this, and is it 
possible to, in the meantime, use DMD's Phobos?

Here's some of the things I've noticed in particular:

* std.algorithm is not split up
* std.algorithm.comparison.predSwitch is missing
* The version of enforce that takes an exception as a template 
argument is missing (ex. `enforce!MyException(condition, 
"message")`)
