template mixins for boilerplate

I am misunderstanding something about using mixins for
boilerplate code.
I've got a set of functions all of which do the same thing:
public static int fctn1() { return other.place.fctn1; }
I can't use a string mixin to generate the code:
template Function(string name)
{
const char[] Function =
"public static int " ~ name ~ "() { return other.place." ~
name ~"; }";
}
struct S {
mixin (Function!("fctn1"));
}
Error: "cannot use a template to add field to aggregate S".
I can't use a template mixin:
mixin template Function(string name)
{
const char[] Function =
"public static int " ~ name ~ "() { return other.module." ~
name ~"; }";
}
Error: mixin templates are not regular templates.
Is there a way to duplicate fctn1 with a different name each time?
