A modern programming language that makes developers happier.

kotlinlang

what is the purpose of `object` ? isn't it basically same as top level members in a separate package?

`object Elvis` defines a singleton (there is only one Elvis)
Not the same because after imports they will look like `Elvis.GREATEST_HITS` and `GREATEST_HITS`.
The former is better IMHO

so basically the purpose is just structure (where to find a function) and accessibility (public/private/ect) right?

And they can implement interfaces, I also use them for "do nothing" interface implementations.

For example the stdlib has the empty list, set and iterator as objects I think.
