[Pharo-project] Strange behavior

[Stéphane Ducasse]

 'abc' replaceAll: $a asString  with: $z asString.
        'abc'

| s |
s := 'abc'.
s replaceAll: $a asString  with: $z asString.
s

        'abc'

while the finder is telling me


 'abc' replaceAll: $a asString  with: $z asString.
        'zbc'

quite confusing…
