Don has recently said that adding dynamic arrays at compile-time looks easy.
I'd also like to have compile-time associative arrays. So you can fill them
inside a CT function (the compiler may try to do the same for AAs created
inside a static this(){}), and save some run time.
Even if such compile-time AAs have to be immutable at run-time they can be
useful anyway.
A smarter implementation of such CT AAs may even use a perfet hashing, to make
them quite fast.
Indeed. I think perfect hashing is one of the primary appeals of a
compile-time AA.
BTW, you can use AAs inside CTFE already. There's probably missing
functionality, though -- create a Bugzilla test case for anything you
find. The primary thing which is missing is that you can't use an AA
literal to populate a runtime AA (this is a backend issue, not a CTFE
limitation). You can get the AA keys and values as arrays, though, so
you could populate the AA yourself.
