but one can think of zip(...) being able to be l-value
@x � @y � @z := map { /foo/ && $_ but unzip(0),
/bar/ && $_ but unzip(1),
/zap/ && $_ but unzip(2),
}, @source;
where argument of unzip is index of the stream to which to "direct"
the value . but then I am not sure where the actual "nzipping" happens
and what does it mean binding to the l-value function.
