text/template: panic in mistyped call #3267
Description
It looks like the text/template type checker is supposed to figure this out? Or at least not panic? http://play.golang.org/p/ArLMq7u57U package main import ( "log" "os" "text/template" ) type T string func main() { m := template.FuncMap{ "f": func() T { return "hello" }, "g": func(s string) string { return s }, } t := template.Must(template.New("main").Funcs(m).Parse(`{{f|g}}`)) log.Fatal(t.Execute(os.Stdout, nil)) }
