[ruby-core:73846] [Ruby trunk Feature#12075] some container#nonempty?

Issue #12075 has been updated by Shyouhei Urabe.


No, the OP wants to detect things that are _not_ empty.  This is not what blank? means.  Also note that blank? in ActiveSupport has different (far more Rails-centric) semantics than what is described in #3.

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’t 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
