    For single line strings it is usually a good idea to chomp them as
    soon as they have been read in from an external data source and
    then only explicitly use a separate newline when it comes to the
    output stage - it avoids all sorts of problems.

    I think you intended something a bit different :) The RHS of 's'
    is missing....

    The (\n)? can't be right either since, if present, a RHS // would then
    the \n too. So I assume you meant thiis to be something entirely

    I could shorten mine to: s{ , (\z)? \Z }{}x though which seems
    to beat.
