I have a function (func MyFunc) whose def ends with

How can I passed the flag.Args() (of type []string) to this function?
Thx

Thanks; I feel much more comfortable with that design having some
literature (as well as the voices of several community members in this
thread) to back it up. I'm suprised this isn't an iss

This explains why you can do stuff like that and why the Go team decided to
make the language work this way.

Hello golang-nuts,
Here are two code snippets with operations on different types. One with
constants and another one with variables. The first one works, the second
one doesn't. Why is it like this? Logically both code snippets shouldn't
work:

Hi Michael,
Can you please explain more in details how you solve this issue? I am also

I understand the slice vs array difference. But in this statement,
intPtr := (*[]byte)(p)
my int
An array is a vector of values in memory. A slice is a small struct that
describes an array stored elsewhere in memory.

hello,
This piece of code prints [10 0 0 0] as expected..
func main() {
i := 10
p := unsafe.Pointer(&i)
intPtr := (*[4]byte)(p)
fmt.Println(*intPtr)
}
But if I convert the unsafe.Pointer to pointer to a byte slice rather than
an array of 4 bytes it prints an empt
Fair enough. Thanks for the explanation. It also seems to imply that the
idiomatic way is to have multiple functions as opposed to abusing variadic
args, which answers the OP's question.

This is where having defaults for function arguments would make for a nicer
API, like python and other langs. Go 2. Maybe.
I agree that the variadic version is not great for a public API, though I
do abuse it in test helpers because it's convenient.

I noticed your “naive explanation” after I sent my message. But I think it is
the real explanation.
Is there a better way to do it in Go? Probably not. The math/big library isn’t
quite as fast as gmp, but it’s probably faster than anything you’d write
yourself. If the numbers were really huge,

I've personally found that when designing an API, it's generally better
to consider two things that are almost but not quite the same as two
things (or, two endpoints if you prefer).
