The 'length' property of an associative array should be usable from @safe code, but isn't.


The following code doesn't compile:

--------------
module assoc;

import std.stdio;

string[int] a = [1: "foo", 2: "bar"];

@safe void main()
{
    writefln("%d items.", a.length);
}
--------------

The compiler output is:

assoc.d(9): Error: safe function 'main' cannot call system function 'length'
