You can write a string mixin that converts a string like:
(a,b) = fun_call(c,d);
into
fun_call(c,d,a,b);
and another one that converts a string for defining functions:
(int, int) fun_call(int c, int d) { ... }
into
void fun_call(int c, int d, out int ret1, out int ret2) { ... }
I've personally used the import expression and string mixins + ctfe
instead of ordinary D imports to implement rather nice language
extensions by parsing the language on module level.
