This will make your shell script work independent of where you invoke it from. Each time you run it, it will be as if you were running ./cat.sh inside dir.

On the other hand while using Traits, composing class has to resolve conflicts.
Class C mixins TA, TB {
bar():void {
foo();
}
}
This code will raise conflict (two definitions of foo():void).
