    # The placeholder_string_matcher plugin exists for backwards compatibility
    # with previous versions of Roda that allowed placeholders inside strings
    # if they were prefixed by colons:
    #
    #   plugin :placeholder_string_matchers
    #
    #   route do |r|
    #     r.is("foo/:bar") |v|
    #       # matches foo/baz, yielding "baz"
    #       # does not match foo, foo/, or foo/baz/
    #     end
    #   end
    #
    # It is not recommended to use this in new applications, and it is encouraged
    # to use separate symbol or string class matchers instead:
    #
    #   r.is "foo", String
    #   r.is "foo", :bar
