extern(C) alias void function() Callback;

template Wrap(alias dg)
{
    extern(C) void Wrap()
    {
        dg();
    }
}

void main()
{
    Callback cb = &Wrap!( () {} );
}

Error: cannot implicitly convert expression (&Wrap) of type void delegate()
pure nothrow @safe to extern (C) void function()

According to Timon Gehr: "'() {}' should be inferred as void function()pure
nothrow @safe." http://forum.dlang.org/post/jib1a2$1jl5$1@digitalmars.com
