D - Associative arrays with dynamic strings

Hi, I would like to do something like this:

char[] [char[]] assoc_array;

assoc_array["Hello"] = "Test";

But this doesn't compile:  cannot implicitly convert wchar[5] to int
The problem doesn't show up if I use: = 3 for example. Any idea?

I've run into this before. You can declare it like this: char[char[]][] assoc_array;

I see you have faced two different problems simultaneously. One was pointed out
by Patrick. (You have defined different type of indices in one order and used
them in reversed order, first is int, second is char[])

But the other problem is with the present D implementation.
String constants have the type of wchar[n], but the assoc array works
only with char[]. It implies you have to cast char[] and wchar[]
very often and vice versa. I hope these kind of problems will be solved
when the specification of D gets clearer.

I think wchar[] is good for UTF8-UTF16-UNICODE representations, but
it is inconvenient to cast string constants always.

Walter surely could give us proper explanation.

I just need to fix dynamic arrays to work with wchar[]'s.
