Feature #5185: Set#merge acts in place but Hash#merge does not
http://redmine.ruby-lang.org/issues/5185

Author: Thomas Sawyer
Status: Open
Priority: Normal
Assignee: 
Category: lib
Target version: 1.9.x


Waste of brain cells to have to learn and recall they are different. The expected method would be Set#merge!, Set#merge would return a new Set instance.

OTOH, why not Set#concat ? Or conversely, Array#merge ?
