hi, @joker-eph 
We come up yet another idea. How about we clone the public function foo() and mark the clone private? 

```
public void foo(%unused: i32) {
return; 
}
bar() {
%x = ...
foo(%x)
}
=> clone change its uses:
public void foo(%unused: i32) {
return; 
}
private void foo_(%unused: i32) {
return; 
}
bar() {
%x = ...
foo_(%x)
}
```
then everything is in order.
