I'm sorry -- the "share" button doesn't seem to be working, or doesn't work
in Firefox or Chrome. And I have a window hung on "waiting for remote
server," so I might have broken your playground.
Here's my code in (hopefully) compileable form for your processor:
package main
impoort "strconv"
// Given:
func map(f(*), a []*, result []*) {
for i, k := range a {
result[i] = f(k)
}
}
func main() {
a := "a" ; aa := "aa"; aaa = "aaa"
mylen := func(k *string) *int {
rv := len(*k)
return &rv
}
map(mylen, []*string{&a, &aa, &aaa}, make([]*int, 3)) // Is this
possible?
one := 1; two := 2; three := 3
myItoA := func(k *int) *string {
rv := strconv.Itoa(*k)
return &rv
}
map(myItoa, []*int{&one,&two,&three}, make([]*string, 3)) // once more,
for profit
map(strconv.Itoa, []*int{&a}, make([]*float, 1)) // Is this a
runtime error?
}
And, yeah... the pointers are a bit of trouble. By the time all of the
wrapping and referencing is done, it's only a little easier than just using
interface{} everywhere with casts. If you don't get type safety with this,
I feel like the syntactic sugar value is pretty modest.
