There's no cognitive load whatsoever: it's calling methods. Always.
Ruby simply gives you no other option. Now it could be very simple
methods to instance attributes, akin to a java getter, but it's still
Furthermore Ruby has a pretty nice convention (sadly not used enough I
think) taken from Scheme where it's possible to postfix a method name
with "!" (note: the "!" is part of the name, there's no magic) to
indicate that this method modifies the object it's called on rather
than simply returning stuff.
