The whole purpose of to_ary, to_str etc, is to support implicit type
conversion for Array/String-like objects into real Array/String for C
defined functions which requires legit typing.  By String/Array-like
object, I mean Delegators, for example.  So in a sense, it's for
performance, by allowing C functions to bypass method invocation.
