Thank you. Are there plans to add a type constraint which would allow this?
Maybe something like this?
func slice[From implements To, To any](from []From) []To { ... }

Is it possible to write a generic function which converts a slice of a
concrete type to a slice of an interface that type implements? Something
like this...
// generic version of []*x -> []X (does not compile)
func gslice[From interface{ ~To }, To any](from []From) []To {
var to []To
Only for exported types. tls.listener isn't

This works but it is somewhat ugly ...
// l is either a tls.listener or a TCPListener
if strings.Contains("*tls.listener", fmt.Sprintf("%T", l)) {
srv.proto = "https"
}

I've tried this but srv.TLSConfig is always non-nil.
package main
import (
"log"
"net/http"
"time"
)
func main() {
srv := {Addr: ":8080"}
go srv.ListenAndServe()
time.Sleep(25 * time.Millisecond)
if srv.TLSConfig == nil {
log.Println("Started HTTP Server on ", srv.Addr)
} else {
It's not how other completions work, it's redundant and makes it harder to
read.

I'll look into this. So far I've spent 30 min on this. :) which dir pattern
should I use for directory completions so that the suggestions don't start with
./ ?
Eg consul agent -server -data-dir ./data
