I have fist edit the Array#index method in order it to return an array of indexes and not a single index (which is the first occurrence it finds). I found it more logical but a user (trans) tells us that it could break the contract of Array#index so I decided to move it into Array#indexes. Eric (drbrain) tells me I should reasonning why I want to add this method ; it's just a point of view : I don't really understand why Array#index return a single index if the parameter is in the array several times. Examples a = [1, 2, 3, 1] a.indexes(1) Return : [0, 3] a.index(1) Return : 0 In my opinion, it's not really logical, 1 is in the array twice Moreover, this pull request doesn't beak anything because we don't edit the Array#index method so programms which were created with previous version of Ruby will work. I hope my post is complete. Have a nice day. -- http://bugs.ruby-lang.org/
