(\1 on the right hand side of a substitution, with the same meaning as $1, has been deprecated for quite some time.)

yeah. that's how i was used to seeing \1. from people learning perl who are used to vi, ex, etc. on the right hand side, it's a no-no.

although, there's a problem with the explanation of your first example. $1 can't hold 'c', it's nowhere to be found. but i understand the difference now. docs are good.
