Which version of the DMD comiler are you using?

When I tried your example with version 2.008 it worked...

---------------
C:\temp>type test.d
import std.stdio;
import std.variant;

void main()
{
        Variant v;
        v = 4;

        writefln("%s", v);
}
C:\temp>dmd test.d
c:\dmd\dmd\bin\..\..\dm\bin\link.exe test,,,user32+kernel32/noi;

C:\temp>test
4

C:\temp>dmd
Digital Mars D Compiler v2.008
