Some reason there's no Array.append? Or, let me rephrase, should there exist
append as an alias to push.

Note the documentation for Array:


self << obj 

          *Append* a new item with value obj to the end of the array.

push(obj...) 

          *Appends* obj to the last of the array.


I've written now at least couple of times array.append(foo) and then changed
the class by myself. After that it came to me - maybe it should be there in
the first place :).
