Installing examples is not working anymore

[itsmylife]

I am trying to install the examples with the command below:

$ go install github.com/prometheus/client_golang/examples/random@latest

but I am getting the following error:

go: github.com/prometheus/client_golang/examples/random@latest (in github.com/prometheus/client_golang@v1.13.0):
	The go.mod file for the module providing named packages contains one or
	more exclude directives. It must not contain directives that would cause
	it to be interpreted differently than if it were the main module.

This was working with the previous version:

go install github.com/prometheus/client_golang/examples/random@v1.12.2

I assume the changes introduced here #1062 are the reason. Especially this line:
https://github.com/prometheus/client_golang/blob/main/go.mod#L31

My Go Version:

go version go1.18.1 darwin/arm64

Maybe we need the examples to use their own go.mod? But that might lead to weird situations…

Or we can reconsider the exclude directive? IIRC it was only added to silence buggy security scanners (that would be confused by the dependency resolution method of Go Modules when faced with circular dependencies).

Both the strategies make sense.
With the new Go workspace features having different modules in a project should be rather easier.
Also, we might already have deprecated the need for the exclude, if I'm not mistaken we have bumped the minimum required Go version since then. And the issue was related to the older Go version. (I might misremembering things).

I've started taking a look at this issue to see if I can help.

1. I'm pretty new to workspaces. Should go.work be committed, or should I add an entry to .gitignore?
2. After I've made my changes how do I validate that I've solved the original issue?
