Thanks a lot Ilya, I expanded now electric-backspace with a wrapper to
handle indented-comments.

see  http://perlmonks.org/?node_id=839593

BTW: I'm trying to realize variable refactoring by searching for the
last my declaration of a given variable.

I noticed that %a and @a are handled differently from $a

(print (sexp-at-point)) will return "$a" but only "a" in the other
cases. Same problem with (backward-sexp)

Cheers

I need this to check if a variable is preceded by a "my" or "our"
statement.

Any suggestions?
