    # From https://github.com/rubyworks/facets/blob/master/lib/core/facets/string/modulize.rb
    # Converts a string to module name representation.
    #
    # This is essentially #camelcase, but it also converts
    # '/' to '::' which is useful for converting paths to
    # namespaces.
    #
    # Examples
    #
    #   "method_name".modulize    #=> "MethodName"
    #   "method/name".modulize    #=> "Method::Name"
    #
    # @param string [string] input, `module/class_name`
    # @return [string] a string that can become a class, `Module::ClassName`

    # replaced by underscores. This is the reverse of {#camelcase},
    # albeit not an exact inverse.
