Disagree hard!
a = append(a[:i], a[i+1:]...)
That’s the recommended implementation of erase(). After this, is the original object referred to by ‘a’ modified? How can you tell?
Let’s pop from a stack:
x, a = a[len(a)-1], a[:len(a)-1]
Did you read that 100x faster than ‘a.pop()’?
Now this:
a = append(a[:i], append(make([]T, j), a[i:]...)...)
This is an operation called “expand.” What does it do? It is an honest question, I have no idea.
These are completely idiomatic examples taken from the Go wiki. They are not readable.
