How can I have an associative array, which uses a

I'm afraid the only viable solution right now is to
implement your
own AA type as a struct with overloaded operators (which is
in fact
what the built-in AAs are lowered to as well).
There are two downside to this, though - besides, of
course, the
fact that you need a custom implementation:
- You cannot pass your type to library functions
expecting a
built-in associative array.
- You lose the convenient literal syntax. This could be
fixed in
the language, though, by providing a rewrite to a variadic
constructor of user types for array/AA literals, thus
eliminating
the need for GC allocations (gah, another thing I just need
to find
the time to write up a DIP for…).

This means, that dlang.org <http://dlang.org> is lying. D
doesn't
provide both a garbage collector and manual memory management.
It
provides a garbage collector and a lousy excuse for manual
memory
management. As much as I love D for it's metaprogramming and
generative
programming, it's not even remotely fit for system-level
programming the
way it claims it is.
I don't mean to be trolling, but it's not the first time I got
grossly
disappointed in D.

Benjamin, maybe you could in your spare time draw a DIP for
Allocators?
This is really very important thing we need for yesterday and
putting all the work on Andrei won't help with it.
Your solution seems to work very well in practice, maybe it would
be possible to adapt it for Druntime/Phobos needs? Or maybe its
already fully designed and only needs polishing and pull request?
Thanks!
