I don't see the point of having a value in a data structure that isn't
used anywhere outside probing but nevertheless lives forever.

I also don't see how it is "cleaner" to assign a value to a variable
in a data structure only to dereference it in a single called function,
when it can be just as easily be passed as argument to that function.
I would call that just the opposite, since it creates the impression
that the variable is needed outside probing when that is not the case.
