Subject: [ruby-core:43840] [ruby-trunk - Feature #5644] add Enumerable#exclude? antonym


Issue #5644 has been updated by trans (Thomas Sawyer).


I'll throw my hat in with #exclude? too. There's been a number of times that I would have liked to have it. "not include?" is a rather common predication and it's nice when code can line up neatly.

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.
