About typequalifier and generic containers.

Once again a post DConf topic.

T[] implicitely cast to cont(T)[] . Isn't it nice ? Yes but, 
Foo!T do not with Foo!const(T), and for good reasons.

This make it very cumbersome to write collections in D in general 
and make them fully usable with the const system.

It has been raised several time by Steven and several others, I'm 
hitting the same problem as well.

Many people raised the need for better collection lib and I have 
to say I do agree. This and the allocator design are the 2 major 
pain point that need to be removed to get a high quality 
collection library.
