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);
}
