I was going through the documentation.
There is a section as below:
<- operator associates with the leftmost
chan<- chan int // same as chan<- (chan int)
chan<- <-chan int // same as chan<- (<-chan int)
<-chan <-chan int // same as <-chan (<-chan int)
chan (<-chan int)
All above 4 scenarios, I did not understand. Please help me to understand.
