Re: [go-nuts] Re: Improvement in text/template/parse/lex.go

Yes, you are correct, if the template is only {{}}'s with no text then there is no benefit, but no penalty, either (i.e., no down side in performance). Once there is any reasonable amount of text (as all templates I have written are), the speed up is noticeable. -Paul On Mon, Jul 11, 2016 at

There are places throughout the standard packages where extra copies happen due to []byte <-> string conversion (like strings.Join(), os.*File.WriteString() etc.) I am assuming they don't use an unsafe-magic way to make aliasing strings and []bytes because they don't want people to shoot them
