This whole chained accessors thing is a definite perl-ism and will do you no favours with people for whom Perl is not a primary language.
Possible return values for write-accessors:
true/false
undef/error message
the previous value
the new value
[I would never have considered the object itself a valid return value until I saw Perl people doing it. I still don't.]
Bah. I've seen Java code doing it. I've seen EcmaScript code doing it. SmallTalk does it pretty much all the time. Besides, I like it :)
