[ruby-core:89029] [Ruby trunk Bug#15123] Enumerable#compact proposal
From:

ruby-core #89029
Issue #15123 has been updated by shevegen (Robert A. Heiler).
I think if the meaning is consistent (e. g. .compact meaning to eliminate
nil values from a given collection) then this seems ok. Perhaps this could
be added for the next developer meeting.

Hi!
While Enumerable does not provide `#compact` method, it requires changing code in some cases to substitute array with enumerator.
For example, to reduce memory usage it's usual to change `large_array.map { to_heavy_object }.chained_methods` to `large_array.lazy...`. However if `chained_methods` contains `compact`, this change will fail. Replacing `compact` with `reject(&:nil?)` fixes it.
What do you think about adding `#compact` to Enumerable?
