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:
template declare_bar(string var_name) {
enum declare_bar =
"auto " ~ var_name ~ " = c_make();" ~
"scope(exit) if(" ~ var_name ~ ") c_free(" ~ var_name ~ ");"
}
void main() {
mixin(declar_var!"b")
}
For example.
That said, given your example, simply using an RAII wrapper
*could* be superior (depends on your actual usecase).
