Issue #14546 has been updated by nobu (Nobuyoshi Nakada).
`Hash#delete` is destructive, so appending `!` doesn't seem making sense.
Rather, a destructive version of `Hash#fetch` feels better.
----------------------------------------
Feature #14546: Hash#delete!
https://bugs.ruby-lang.org/issues/14546#change-70637

----------------------------------------
Hash#delete currently returns nil if a given key is not found in the hash. It would be nice to have a way to check that the key was present in the hash. This can be accomplished with with a block, but it would be nice to have some sugar for this.
~~~ ruby
{ a: 'a' }.delete(:b) # => nil
{ a: 'a' }.delete(:b) { |key| raise KeyError, "key not found #{key}" } # => KeyError (key not found: b)
~~~
I'd like to propose a Hash#delete! method:
~~~ruby
{ a: 'a' }.delete!(:a) # => 'a'
{ a: 'a' }.delete!(:b) # => KeyError (key not found: :b)
~~~
