[thelist] pass by value in JavaScript?

[Michiel Trimpe]

Hi Matt,

It might feel ugly but it is the best way to go. Most programming
languages offer some sort of copyOf() method but I couldn't find it in
any reference so I don't suppose JS's Option object has one.

If referencing suffices then that would be the best though but I
assume that won't be possible.
