Revamping associative arrays

[Andrei Alexandrescu]

Associative arrays are today quite problematic because they don't offer 
any true iteration. Furthermore, the .keys and .values properties create 
new arrays, which is wasteful.

Another issue with associative arrays is that ++a[k] is hacked, which 
reflects a grave language limitation. That needs to be replaced with a 
true facility.

Any other issues with AAs that you want to see fixed, and ideas guiding 
a redesign?


Thanks,

Andrei
