List Operators (Rightward)

On the right side of a list operator, it has very low precedence, such that it controls all comma-separated expressions found there. The only operators with lower precedence are the logical operators ``and'', ``or'', and ``not'', which may be used to evaluate calls to list operators without the need for extra parentheses:

    open HANDLE, "filename"
        or die "Can't open: $!\n";

See also discussion of list operators in Terms and List Operators (Leftward).
