Maybe it needs a bit more explanation. It goes according to this
idea:
http://en.wikipedia.org/wiki/Principle_of_least_astonishment
If I define:
Foo[] a;
I expect those Foo items to be mutable.
If I see:
int[Foo]
I expect those Foo keys to be mutable.
If I see:
int[Foo]
I expect those Foo keys to be mutable.
If I see:
int[immutable Foo]
I expect those Foo keys to be immutable.
If I see a int[Foo] and I get immutable Foo keys, I am astonished.
Not doing what I am saying here will add another special case to
D language. Avoiding many special cases is one the reasons I
program in D instead of C++.
