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.

Just a note:  The map bug theoretically applies to all the other higher-order ranges that were made nested.  It's just that I only stumbled on it for map.  We really need Andrei's input about what to do about this, since he originally made the changes, is the "owner" of std.algorithm, etc.

After Walter and I discussed this yesterday, we believe it's best to move forward with the nested struct idiom, which is of very significant usefulness. He has fixed 5939 (Walter, could you please update bugzilla?) and is confident he can tackle the other remaining related issues.

That's good to hear. It's definitely a great idiom, and it wouldn't be fun to have to go and undo all of those changes just for 2.053 and then put them back again once the compiler issues were fixed.

5939 isn't a compiler bug.
