Re: list comprehension

Actually I would suggest NOT adding Perl6, because the best way to create a Set is not to use “list comprehension”, but to just call `.Set` That whole page is about Set Builder Notation, but Perl6 doesn't actually have such a thing. You create a Set through a method call, or a subroutine call.

Dear Brad, Thanks very much for the answer. I have been playing with your examples in the code below (and learned a lot!). Based on your insight, I would suggest these solutions to be added to the wikipedia: https://en.wikipedia.org/wiki/Set-builder_notation#Parallels_in_programming_languages

Please be aware that WHERE will give you the actual memory address of an object, but moarvm has a moving garbage collector, which means that objects can change their memory location. at the moment it will only happen up to two times, i believe. you'll probably have a better result with .WHICH for
