Subject: [ruby-core:55189] [ruby-trunk - Feature #8458][Rejected] Array#merge/merge!


Issue #8458 has been updated by matz (Yukihiro Matsumoto).

Status changed from Open to Rejected

Generally speaking, arrays are not argument lists.  This method is specific to argument lists.
Thus Array is not the right place for the method.

Feature #8458: Array#merge/merge!
https://bugs.ruby-lang.org/issues/8458#change-39551

Author: boris_stitnicky (Boris Stitnicky)

Very simple method can be defined:

class Array
  def merge! other
    require 'active_support/all' # can't use #tap, see #8457
    tail = extract_options!
    other_tail = other.extract_options!
    concat( other ) << tail.update( other_tail )
  end
end

When pondering about where this method should dwell, it seemed to me, perhaps in the core itself? Am I deluding myself?
