[dmd-beta] Last (really, this time I mean it!) D2 beta 2.057

[Steve Schveighoffer]

Just tested the latest master git branch (I saw that you made some changes Walter), and dcollections compiles and passes unit tests.

And it seems like 6912 fix is still intact (code in that bug fails to compile).  So I think we're good as far as this issue is concerned.
