The OP did suggest a comprehension version, which I personally prefer --
but thought it " feels a bit janky" -- I can say that lambda/filter feels
even jankier to me :-)
you could create a new class for holding a collection (or set) of members.

and then you'd be writing this code in your class -- but that's a good
thing, as you could then refactor it to optimize it or use persistent
storage, or ....
Anyway, I agree that once. you need to customize your matching function,
you might as just write the code.
