Every method from MRI's core classes is written in C. This means Method#arity always returns -1 for methods with a variable number of arguments. This is not the case with Rubinius, where, for example Array#slice! is implemented in Ruby and has arity -2, since is defined as def slice!(start, length = undefined) |
