It was more a joke than an argument. Learning Go was like that Nate Bargatze sketch from SNL where he plays George Washington.
"Sir we need a loop" "We will have for loop, and nothing else." "Only one lo.." "Only for loop"
"Sir we need a loop" "We will have for loop, and nothing else." "Only one lo.." "Only for loop"
It’s versioned because the function signature differs but the abstraction itself doesn’t.
That’s not to say that Go doesn’t have multiple different abstractions for common problems too. Just that your specific argument here is incorrect.
