If you are using a kind of "temp values" as an optimization, and
these values do not affect the external behavior of the class,
you can declare those values as 'mutable', which allows modifying
them even from a const method.

(Well, nothing stops you from making them mutable even if they did
affect the external behavior of the class. What I mean is that this
should be done only when it does not, or else the class becomes badly
designed.)
