SequenceableCollection has with:do:.
Add
with: other count: testBlock
|r|
r := 0.
self with: other do: [:x :y |
(testBlock value: x value: y) ifTrue: [r := r + 1]].
^r
I have this in my library anyway. Now
distanceStrand1: a strand2: b
^a with: b count: [:x :y | x ~= y]
#with:do: already checks that the sequences have the same size;
it's too confusing if the error reported in this case is different
from the error for #with:do:.

Morales Durand:
^ (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) ]
