string[string][] Dict; //sure ok.
alias string[string][] dict; //Error
void main()
{
Dict = [["Cow":"moo" ],["Duck":"quack"]];//cool
Dict ~= ["Dog":"woof"]; //No prob.
assert(Dict==[["Cow":"moo"],["Duck":"quack"],["Dog":"woof"]]);//looks legit
//dict temp = [["Cow":"moo" ],["Duck":"quack"]];//Error
//string[string][] temp2 = [["Cow":"moo" ],["Duck":"quack"]];//Error
//And My favorite one of all:
//auto temp2 = [["Cow":"moo"],["Duck":"quack"]]; //Error
auto temp3 = tuple([["Cow":"moo"]]);//works. Variant as well.
}
With everything commented out, Dict works just fine from way up there.
But Tuple, Variant, tls,
Those are the only way to get this to work.
The specific error it gives is:
Error: Integer constant expected instead of "Cow"

A little reformatted:
import std.typecons: tuple;
string[string][] aa1; // OK
alias string[string][] AA;
void main() {
aa1 = [["A": "B" ], ["C": "D"]]; // OK
aa1 ~= ["E": "F"]; // OK
assert(aa1 == [["A": "B"], ["A": "B"], ["E": "F"]]); // OK
auto a2 = tuple([["A": "B"]]); // OK
AA a3 = [["A": "B" ], ["C": "D"]]; // error
string[string][] a4 = [["A": "B" ], ["C": "D"]]; // error
auto a5 = [["A": "B"], ["C": "D"]]; // error
}
It gives the errors:
test.d(9): Error: Integer constant expression expected instead of "A"
test.d(9): Error: Integer constant expression expected instead of "A"
test.d(9): Error: Integer constant expression expected instead of "C"
test.d(9): Error: Integer constant expression expected instead of "C"

(In reply to comment #2)
This might be a dup of bug 5448.
It is not *exactly* the same, but they do overlap.
Thank you for pointing that out.
Something not mentioned in bug 5448 is that alias does not work with AA,
Although that might be implied.
If you feel that this cuts the difference too close, either close it or I will.
I apologize, I didn't quite understand all of the reasons it would not work
when I opened the ticket.
