For now this makes a few existing functions available as methods, e.g.
mylist->filter(filterexpr)->map(mapexpr)->sort()->join()
It's a lot easier to read than:
join(sort(map(filter(mylist, filterexpr), mapexpr)))
When we add new methods for List, Dict, etc. we can now make them local
to those objects, instead of adding them globally.
I decided to use "->" because of the similarity with C pointer usage.
It would be nice to use ".", but I'm quite sure that won't be backwards
compatible, especially when using a Dict.
Comments are welcome!
