Subject: Array#index block and rdetect

Tiny RCR suggestion:

Array#index optionally take a block like Enumerable#detect does.

    ['a','b','c'].index{|e| e == 'b'}  # => 1
    ['a','b','c'].index{|e| e == 'c'}  # => 2
    ['a','a','a'].index{|e| e == 'a'}  # => 0
    ['a','a','a'].index{|e| e == 'b'}  # => nil

Question: why isn't #index a method of Enumerable, considering 
#each_with_index is? (FYI: 'alias find detect'.)

Lastly, what about an rdetect?
