        foo $= ( bar, quux );  # provide scalar context to both sides
        foo @= ( bar, quux );  # provide list context to both sides

        for ( foo @, bar $, quux ) {
                # iterates over foo and quux,
                # but evaluates bar before quux.
        }

This is very harmonious with the provision of two sets of operators
for numeric and string comparisons.
