7.24 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 7.2.
