You are right, c# does too much. But Go makes it far more work to do basic things - list comprehension for example (what is everyones obsession with for loops?). An opinated language with one way to do things sounds great, but not at the expense of basic niceities you get in other languages.
arr2 := []int{}
for i := range arr1 {
if arr1[i] > 9 {
arr2 = append(arr2, arr1[i] * 2)
}
}
var arr2 = arr1.Where(x => x > 9).Select(x => x*2);
var arr2 = from x in arr1 where x > 9 select x*2;
arr2 = [x * 2 for x in arr1 where x > 9]
(setf arr2 (loop for x across arr1 when (> x 9) collect (* x 2)))
It’s not inherent complexity though, just personal preference. I grew up writing for loops so they’re second nature to me and I grok them instantly in a single pass, whereas some list comprehensions require a re-read (particularly if they’re nested).
Different strokes, that’s all.
