^ (1 to: self size) count: [ : i | (self at: i) ~= (aString at: i) ]

With that code I get a few problems but this is working

distanceStrand1: aString strand2: aString2
    aString size == aString2 size
        ifFalse: [ DomainError signal: (self messageFor: aString strand2: aString2) ].
    ^ (1 to: aString size)
        count: [ :i | (aString2 at: i) ~= (aString at: i) ]
