Very insightful.
I am relatively new to go, but I would like to make a few observations.
1. When the issue of keyword arguments has come up before, usually someone
suggests passing a struct as the function argument. Did you try this? It
might be worth mentioning in your analysis, if only to g
Very in-depth and interesting.
Although I agree with most of the points, I think a better use of interfaces
would address some of your concerns, and have more maintainable code.
Whenever I see a type switch it screams to me “use an interface and
restructure. “

When i change the value U at 0 index , It changes the value of t and u at
zero index why it is not changing the value of S. Please Explain I got
stuck here.
package main
import (
"fmt"
)
func main() {
var s []int
var t []int
s= make([]int,3)
s[0]=100
s[1]=200
s[2]=300
t=append(s,400)

You may be right. On the other hand, I think I've already gone far enough
down the interface road to have collected most of the ga

Hi all, I'm trying to learn how to write a linter (because long weekend,
etc)
I looked at Fatih's very fine blog post (
https://arslan.io/2019/06/13/using-go-analysis-to-write-a-custom-linter/)
as well as the one that precedes it, although I was a LOT lost reading that
one.

I'd like to truncate a float64 to just 2 decimal places (in base 10), but
math.Trunc is not helping me here... ideally I put 0.29 in and I get 0.29
out.
Suggestions? Playground examples appreciated.
package main
import (
"fmt"
"math"
)
// truncate off e
You've fallen into a common trap. Base 2 floating point values cannot
represent most decimal values precisely. This is why you should never,
ever, do a simple equality test involving a F.P. value derived from a
calculation. You always have to apply an epsilon to define a range within
which the two
Picking the first decimal library on pkg.go.dev, what about

Floating point math has many
