Print it:
string copyReplaceAll: 'you' with 'AA'

Literal strings are mutable by not in length so you can easily do destructive
changes in some special cases where you're sure that length doesn't
change. Thus the following is ok:

string replaceAll: $a with: $b

I think mutable literal strings are a bad thing.
