pressing it multiple times results in:
```gdscript
@warning_ignore("shadowed_global_identifier", "shadowed_global_identifier")
```

Shadowing a global function with a method of script:

```gdscript
@warning_ignore("shadowed_global_identifier")

```gdscript
@warning_ignore("shadowed_global_identifier")
static func print_debug(msg: String):
    pass
```
