How about "some?".


----------------------------------------
Feature #12075: some container#nonempty?
https://bugs.ruby-lang.org/issues/12075#change-57003

----------------------------------------
I sometimes write following code.

```
ary = some_metho_returns_nil_or_empty_container() # nil or "" or [] or {}

if ary && !ary.empty?
  #  some code
end
```

But the condition `ary && !ary.empty?` is too long and complex.
Though Ruby 2.3 introduces `&.`, but this can”Ēt be written as `ary&.empty?`.

One idea is add `nonempty?` write as `ary&.nonempty?`.

akr: `nonempty?` is not good name because human is not good at handling 

This discussion matches following core classes:
* String
* Array
* Hash
