[Pharo-project] String mathematical operations

We still have a lot of awkward methods on String for doing math: String >> #* arg ^ arg adaptToString: self andSend: #* Who is relying on them? I would like to deprecate them all :D I guess some binary math selectors might make sense String >> #* count ^ self class new: self size * count streamContents: [ :stream| count timesRepeat: [ stream << self ]]. cami
