Re: What is the purpose of tables.allValues()?

Maybe I misunderstand you, but doesn't it depend on the implementation, and 
aren't there sometimes advantages to doing it this way? 
<https://en.wikipedia.org/wiki/Hash_table#Separate_chaining_with_linked_lists>? 
In one of my C++ projects, I store multiple values for a key, and simply search 
at the key. If the list is short enough then this isn't a problem, and in this 
particular project the list has been short enough that it has never been a 
problem.
