Subject: [ruby-core:70720] [Ruby trunk - Misc #11520] Inconsistent behavior	in Array#compact!

Issue #11520 has been updated by Hal Brodigan.

Tracker changed from Bug to Misc

Ah, I was unaware that was the intention. I guess I should use `.tap(&:compact!)` instead. This issue can be closed.

Misc #11520: Inconsistent behavior in Array#compact!

I noticed that `Array#compact!` sometimes returns `self` and other times `nil`. This behavior was a bit confusing.

    [].compact!
    # => nil
    
    [1].compact!
    # => nil
    
    [nil].compact!
    # => []
    
    [1, nil].compact!
    # => [1]

I would prefer that `Array#compact!` either always returns `nil`, or always returns `self`.
