fix issue 8737 Unqual for AA

[monarchdodra]

http://d.puremagic.com/issues/show_bug.cgi?id=8737

Unqual did not work with AAs.

This is mostly because an AA with a const KeyType is considered non-mutable, even if the AA's general type is not const. This fixes this by Unqualing the Key Type directly.

Examples in the unittests. Non of these unit tests worked without the fix.

Wait, why is this merged!?
Unqual template removes just only top qualifier. Then, the top qualifier of associative array type and the qualifier of its value type is different.
Unqual!(const(V[K])) should be const(V)[K], should not be V[K].

Looking into it.

I've seen the unittest and changed Unqual implementation.
Now your change breaks the behavior of Unqual which was consistent.

And more, you should not have fixed bug 8705 by changing Unqual behavior. For the purpose, you should have made private template.

[monarchdodra]

Yes, you are correct actually.

I figured out I did not actually need to change unqual. Give me 5 minutes?
