Bug #11327: Improve duplicate key warning.

• Status: Closed
• Assignee: zzak (zzak _)
• Target version: -
• ruby -v: ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]
• Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN

[superdealloc (Andre Medeiros)]

This change rephrases the duplicate key warning, which causes some confusion.

Before:

/Users/andre/bug.rb:4: warning: duplicated key at line 5 ignored: :max_instances

After:

/Users/andre/bug.rb:4: warning: key :max_instances is duplicated and overwritten on line 5

[zzak (zzak _)]

If matz will approve, and no objection, I will commit it.

[matz (Yukihiro Matsumoto)]

Agreed.
