You apparently live in a halcyon world of data cleanliness where CSV data
is so well behaved.

In my world, I more typically deal with stuff like

data1.csv:
--------------
name,age,salaryK
John,39,50
Sally,52,37

data2.csv:
--------------
name,salaryK,age
Juan,47,31
Siu,88,66


I'm likely to define different namedtuples for dealing with this:

    NameSalAge = namedtuple('NSA','name salary age')
    NameAgeSal = namedtuple('NAS','name age salary')

Then later, indeed, I might ask:

    if employee1.salary == employee2.salary: ...

And this would work even though I got the data from the different formats.
