Ew, that’s awful. Go is not one of my programming languages but I had always held it in high esteem because Ken Thompson and Rob Pike were involved in it.
Honestly, it does not happen often that I have a ln unused variable that I want to keep. In my mind it is the same thing when wanting to call a function that does not exists. Also my editor is highlighting error Long before I try to compile, so this is fine too for me.
The underscore is used in production code too. It’s a legitimate way to tell the compiler to discard the object because you don’t intend to use the pointer/value.
Is this a hard error? Like it doesn’t compile at all?
Isn’t there something like
#[allow(unused)]
in Rust you can put over the declaration?Yes it is a hard error and Go does not compile then. You can do
_ = foobar
to fake variable usage. I think this is okay for testing purposes.Ew, that’s awful. Go is not one of my programming languages but I had always held it in high esteem because Ken Thompson and Rob Pike were involved in it.

Never really coded in Go outside of trying it out, but as far as I know it’s a hard error.
