Summary: Regexp#+@ can't be overridden

Initial Comment:
It seems that +/regex/ is always /regex/, and can't be overridden. /regex/.+@ can be overridden:

$ ruby -e 'p +//'
//

$ ruby -e 'p //.+@'
-e:1: undefined method `+@' for //:Regexp (NoMethodError)
$ ruby -e 'p(+//.+@)'
-e:1: undefined method `+@' for //:Regexp (NoMethodError)
$ ruby -e 'class Regexp; def +@; "+#{self}" end end;p(+//.+@)'
-e:1: undefined method `+@' for "+(?-mix:)":String (NoMethodError)
$ ruby -e 'class Regexp; def +@; "+#{self}" end end;p(+//)'
//
$ ruby -e 'class Regexp; def ~; "+#{self}" end end;p(~//)'
"+(?-mix:)"
