This seems like it only would work if you know that there 
wouldn't be any allocations. I don't really know though.

Below is a little more generic:

template gc78f(alias f)
{
    void gc78f(T...)(T what) @nogc
    {
        import std.stdio;
        alias fType = void function(T) @nogc;
        (cast(fType)&f!T)(what);
    }
}

void main() @nogc
{
    import std.stdio;
    string x = "hello world!";
    gc78f!(writeln)(x);
}
