Which operator should I use?

[wangshun1121]

I wonder if there's an operator that can:

Input channel:

input = Channel.from([a,b],[1,2,3])

then I wonder if there's an operator:

input.anyOperator(by: 0).view()

with output:

[[a,b],1]
[[a,b],2]
[[a,b],3]

or other parameter such as:

input.anyOperator(by: 1).view()

with output:

[a, [1,2,3]]
[b, [1,2,3]]

How about this:

ch_a = Channel.of('a', 'b')
ch_b = Channel.of(1, 2, 3)

// one way
ch_a.collect().combine(ch_b).view()

// or the other
ch_b.collect().combine(ch_a).view()
