RubySpec #7803: RDoc documentation: `Array#&` clarification

Author: sawa (Tsuyoshi Sawada)
Status: Open
Priority: Normal

Target version:
In the RDoc documentation for `Array#&`, it does not mention whether the order of the elements in the returned array preserves the order in the receiver. There is a question raised regarding this point in stackoverflow:
http://stackoverflow.com/questions/14764135/is-order-preserved-in-arrays-when-intersection-is-done
and it mentions that that is included in the test for RubySpec
https://github.com/rubyspec/rubyspec/blob/master/core/array/intersection_spec.rb#L16
so it looks like that is taken for granted, but it is not guaranteed. If it is indeed a feature, then that should be written in the document. If not, (meaning the order might not be preserved in a future implementation), then that should also be mentioned in the document as a warning. The documentation for `Array#-` makes that point clear:
Array Difference---Returns a new array that is a copy of the original array, removing any items that ...
so, perhaps the docmentation for `Array#&` should be written along the same line.
