What version of Go are you using (go version)?

go1.10.3

What operating system and processor architecture are you using (go env)?

the same to macbookpro2015

What did you do?

https://play.golang.org/p/tyV3T-pkUy6

func test(i ...interface{}){}

a := []int{1,2,3}
test(a...)
// cannot use a (type []int) as type []interface {} in argument to test

why it can't be complied? a... is not equal to a[0], a[1], a[2] ???

What did you expect to see?

i suppose that ellipsis operator really split the slice and pass to the function as variadic parameter.
so make code like above success to be complied
