Thank you Tobias and Herbert for the answers
Interestingly
Squeak 4.3
--------------
('a' respondsTo: #first) == (String canUnderstand: #first)
evaluates to true
(Character respondsTo: #cr) == (Character canUnderstand: #cr)
evaluates to false
Pharo 1.4
-----------
the same as Squeak
Cuis 4.0
---------
true in both cases.
