Issue #20738 has been updated by byroot (Jean Boussier).
There are several Rails codes that can be improved with this feature.
As one of the maintainer of the code you linked to, I agree with @jeremyevans0 that it's currently fine as it is. I wouldn't use such feature if it was added. ---------------------------------------- Feature #20738: Removing a specific entry from a hash literal https://bugs.ruby-lang.org/issues/20738#change-109784 * Author: ursm (Keita Urashima) * Status: Open ---------------------------------------- Sometimes I want to decide whether or not to add a particular entry to a hash depending on a condition. If the entire hash does not use nil, I can use Hash#compact. ```ruby { foo: 1, bar: bar? ? 2 : nil }.compact ``` But if I want to remove only a specific entry while leaving the other nil, it is somewhat cumbersome. I have to either assign the hash once and change it destructively, or use Hash#reject. ``` ruby h = { foo: 1, baz: nil } h[:bar] = 2 if bar? ``` ``` ruby { foo: 1, bar: bar? ? 2 : :drop, baz: nil }.reject {|_, v| v == :drop } ``` As a suggestion, how about a special value that indicates an invalid key for the hash? With this, the above example could be written like this: ``` ruby { foo: 1, bar: bar? ? 2 : Hash::DROP, baz: nil } #=> {foo: 1, baz: nil} ``` -- https://bugs.ruby-lang.org/
