Re: [go-nuts] go run, add string value definition with space

Hi! Not an expert at all, but it seems the format is "package-qualified.identifier=value", with value being able to just contain spaces out of the box, so running: go run -ldflags="-X 'main.MyVar=this is a string'" main.go works for me. Note that for parsing the whole thing correctly, the whole

Re: [go-nuts] In golang spec, if it cast the variable, pointer that cast returns is changed?

Hi, Note that this has nothing to do with casting. `after` and `before` are not pointers, they're plain old `int` variables (or `DefinedInt` in your example but that does not change anything). When you do `after := whatever`, you're declaring (and assigning) a new variable `after` to hold the

I guess this defeats what you were trying to accomplish, but does this answer your needs? https://play.golang.com/p/5kPX8F_u24l Cheers, On Fri, Aug 26, 2022 at 9:42 AM Frank Schröder wrote: > Thank you. Are there plans to add a type constraint which would allow > this? Maybe something like

Re: [go-nuts] Generic interface compiles with incorrectly instantiated types

Hi, I'm not a generics expert either, but I think there is a misunderstanding here: The A in the Wrap[A any] is not the same as the A in Val[A any]. When you instantiate the Extract function with Extract[string], it expects a Wrap[string], which is, in fact, just a type implementing isWrap. The
