Nein.
$ ri Array#delete
----------------------------------------------------------- Array#delete
array.delete(obj) -> obj or nil
array.delete(obj) { block } -> obj or nil
------------------------------------------------------------------------
Deletes items from _self_ that are equal to _obj_. If the item is
not found, returns +nil+. If the optional code block is given,
returns the result of _block_ if the item is not found.
a = [ "a", "b", "b", "b", "c" ]
a.delete("b") #=> "b"
a #=> ["a", "c"]
a.delete("z") #=> nil
a.delete("z") { "not found" } #=> "not found"
