The OP's proposal seems to have a very narrow focus, whereas the
generator approach can handle a much wider range of queries:
sum(1 for x in persons if x.name == "olle" and x.country == "se"))
sum(x.salary for x in persons if x.name == "olle"))
By the time one has looked up the syntax for the augmented count
method, remembered the existence of something like "attergetter" [sic]
and nutted out its spelling and usage, somebody else using generators
would have the job and gone to lunch :-)
YAGNI. Case dismissed.
