[dmd-beta] What are the current known blockers for 2.053?

[Don Clugston]

Known regressions relative to 2.052:

DMD:
5976   "variable used before set" scope(failure) + ref foreach, only with -O
5965   [2.053 beta] map rejects a predicate with anon-func and nested func

PHOBOS:
5939   Cannot copy std.algorithm.map
----
Have I missed any?

BTW if you find a regression, please enter it in Bugzilla. They are
quite difficult to track if they're only reported here.
