Subject: [ruby-core:43940] [ruby-trunk - Feature #5644] add Enumerable#exclude? antonym


Issue #5644 has been updated by rosenfeld (Rodrigo Rosenfeld Rosas).


I think I've misunderstood the question posed by Nikolai. I've just read it again but I think that the other meaning presented by him doesn't make any sense. "does the array contain the elements that should be excluded?". Really? I read this like in English:

Does [1, 3, 5] exclude 4?

Ask someone that doesn't know anything about programming and see what will she answer to this question.

Feature #5644: add Enumerable#exclude? antonym

Please add Enumerable#exclude? as antonym of Enumerable#include?

This allows me to construct Boolean expressions more pleasantly:

  if File.exist? some_file and not some_list.include? some_file

Can be written as:

  if File.exist? some_file and some_list.exclude? some_file

Thanks for your consideration.
