For example, something like the following:
```d
void main() {
char accepted_type;
char* non_accepted_type;
if (__traits(isPointer, typeof(accepted_type))) {
// The type is not accepted
}
else { /* The type is not a pointer so its accepted */ }
if (__traits(isPointer, typeof(non_accepted_type))) {
// The type is not accepted
}
else { /* The type is not a pointer so its accepted */ }
}
```
In that example, the first comparison will execute the second
branch and for the second comparison,
it will execute the first branch. Of course, this trait doesn't
exist I used an example to show what I want
to do. Any ideas?
