in reply to $1[

You are using a screwdriver to stab someone. While that is also deadly, the right tool makes a much cleaner cut:
$_ =~ tr/()/[]/;

    Problem I was solving was more complicated, I only left some context in which I have used square brackets. I've simplified for show a problem of interpreting '$1[', which looks to me as a bug.

      No, for sure it is not a bug. When in doubt use the ${name} form inside of double quoted strings, or other contexts with similar rules. This could have happened with a var named $foo

      demerphq (dmq but i can't be bothered to log in)

        That was me. Can't even remember my account name apparently. :-)
