Is it too late to switch to Ruby?

That's not a joke; it's an excellent language that will lead to very elegant
solutions here.

Premature optimization is the root of all evil. In this case, if you need an
object, even as a compilable comment, create an object.

Put another way, it's easier to make clean code fast than make fast code
clean. Clean code is easy to read and understand. Create an object that
duplicates its instances of these heavy members. Then get your program to
work, and then think about _explicitely_ replacing the heavy members with
references to shared single instances of their data.

Write them yourself. In Ruby, they would be...

@@one ||= [1,2]

one is a class variable, and if it's not assigned yet then create an array
and plug it in.
