I ran into this error when trying to create a module with a single Go file and import it from GitHub:
``` predeclared any requires go1.18 or later (-lang was set to go1.16; check go.mod) ``` After some digging, I learned that since Go 1.18, external modules need a go.mod file. Without one, the language spec defaults to Go 1.16. The tricky part is, it's not obvious at first glance that this error is caused by a missing go.mod file in the module you're trying to import. I was thrown off because the go.mod file in my main project had 'go 1.22.6' in it. It'll be helpful if the error message could specifically mention that it's looking for a go.mod file in the module being imported. What do you think?
