Introduction

Problem

If multiple methods with the same name are defined, there needs to be some way of determining which method a call refers to. The general rule is given on p. 123 of Programming Ruby. But questions still remain.

Questions

  • Is it possible to get unexpected behavior if one of the modules you are using is "enhanced" to contain a new method that happens to conflict with a name of an existing method?
  • Is it possible to refer to these methods using a qualified name?
  • Is it possible to use method aliasing to resolve the ambiguity?
  • What approach does good o-o design dictate?
