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.

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about this, since he originally made the changes, is the "owner" of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.

    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.
