value, so "b = null;" will have no effect at the end of the call.
Use pass by ref:
void c_free(ref bar* b) { b = null; }

Mixin templates can only insert declarations, not arbitrary

To add to that, if you want to mixin arbitrary code, then you can
use a string mixin

Can we not use scope(..) in a mixin template?
struct bar {}

mixin template Foo() {

scope(exit) if(b) c_free(b);

void main() {
mixin Foo;

I get
