That wouldn't be a bad idea, actually. The current AA

so horribly broken, and so wrong in so many ways (there are at

bugs related to AA's, some of the worst of which are 11037,
11025,
10916, 10525, 10381, 10380, 10046, just to name a few), that it

a world of good to get rid of them altogether, and then
reintroduce a
properly-designed library solution for them.
Of course, in the meantime everyone whose code breaks because
of that
will form a mob to lynch me, so I'll have to survive long
enough to get
the library solution working first. :-P

This demonstrates an interesting issue.
I think the primary reason why you are complaining about AAs is
not because their implementation is flawed but because you can't
fix it without dmd's internals knowledge :)
I always consider ability to hack dmd as important skill (at
least in better language understanding because it is not defined
by standard but by reference implementation) in D and that's why
I am skeptical about many ideas proposed in form of DIPs -
(unless they are proposed by those folks whose names often appear
in dmd git commit log) because such proposals are not
implementable without dmd's knowledge.
I remember one point made recently by one regular D forum
participant that it is more important 'to know the language
itself', 'to be abstract from one particular implementation'
rather then knowing 'dirty implementation details' to propose
DIPs and that those who know dmd will eventually implement DIPs -
yet number of DIPs is close to 50 and judging by ratio
implemented DIPs/total DIPs it obvious that such assumption
doesn't hold.
As a result community is stuck with many features of language are
flawed but they can be hardly fixed - plenty discussions and DIPs
are generated but problems are not moved by an inch.
I think if a person who has druntime/phobos commits to fix some
issue but no dmd's one should ask in a forum thread/directly
address to Walter/Kenji for a help request (addressing Walter
should happen without hesitation because he is the first to be
blamed :) ).
