Subject: [ruby-core:49966] [ruby-trunk - Feature #7394] Enumerable#find ifnone parameter could be non-callable


Issue #7394 has been updated by mame (Yusuke Endoh).


Oh, I didn't realized that this ticket was from github pull reqeust.
Thank you for your importing work!
But, the fact remains that this proposal was not accepted by the 2.0.0 deadline.  Sorry.

It is unfortunate that people misunderstands that github pullreq is the right way to request a feature to Ruby.
Is it impossible to stop (or automatically reject) pullreq?

Feature #7394: Enumerable#find ifnone parameter could be non-callable

from github:
https://github.com/ruby/ruby/pull/186

In trunk the Enumerable #find method ifnone parameter has to be callable or nil. I found that sometimes I want to return a simple value without wrapping it in a proc. This pull request adds support for non-callable defaults when no items match.

(({a = [1, 2, 3]}))

The current behavior
(({a.find(proc { :foo }) { |x| x > 3 } #=> :foo}))

With patch
(({a.find(0) { |x| x > 3 } #=> 0}))
=end
