Bundler 2.1.0.pree.1 is the expected version.

ruby-core #92802
Issue #15323 has been updated by nobu (Nobuyoshi Nakada).
IIRC, at the last meeting (20190522), the conclusion was that this method should select non-nil values only, like as `Array#compact`.
Am I correct?

----------------------------------------
This is a proposal for a combined `filter` + `map` method (https://bugs.ruby-lang.org/issues/5663).
This method both filters and maps the elements of an enumerable in just one iteration:
~~~ ruby
(1..10).filter_map { |i| i * 2 if i.even? } #=> [4, 8, 12, 16, 20]
~~~
