Issue #5915 has been updated by headius (Charles Nutter).


Is there a test for this? If not, perhaps one should be added.

I'm fixing http://jira.codehaus.org/browse/JRUBY-6776 and would like to know that the behavior is being tested.

Bug #5915: Array#join with explicit nil should not use $,
https://bugs.ruby-lang.org/issues/5915#change-28407

Author: john_firebaugh (John Firebaugh)
Status: Closed
Priority: Normal
Assignee: naruse (Yui NARUSE)
Category: DOC
Target version: 2.0.0
ruby -v: ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin10.8.0]


=begin
The documentation for Array#join says that the default argument is $,. But:

  $, = ","
  [1,2,3].join(nil) #=> "1,2,3"

Based on the documentation (and the POLS), I would expect "123".
