Using DMD 2.050, when trying to assign a value to an associative array that is
not the type of the AA results in an ICE.

Here are two test cases:

import std.variant;
void main() {
    Variant[string] a;
    a["ICE?"] = 1;
}

------------------------

struct ICE {
    ICE opAssign(int x) { return this; }
};
void main() {
    ICE[string] a;
    a["ICE?"] = 1;
}

Note that:

void main() {
    Variant[string] a;
    a["ICE?"] = Variant(1);
}

compiles correctly. See http://d.puremagic.com/issues/show_bug.cgi?id=2451
