Implicit conversion from null in custom type

I'm trying to write a type which (to some extent) emulates
built-in AAs.
One thing I'm having trouble with is null function parameters:
void fun(S s) {}
void main() { fun(null); }
How can S implement implicit conversion from null?
I've already tried "alias this" and a constructor taking
typeof(null).
