Looking for an app w/ mult. versions of a dependency

[George Hartzell]

Hi All,

I'm working on improving the Spack (https://spack.io) package managers
support for Go-based application
(https://github.com/spack/spack/issues/13023).

I'm trying to wrap my head around what Go's support for simultaneously
using multiple major versions of a dependency means to Spack.

To that end, I'm looking for an otherwise simple application that uses
Go modules and depends on multiple versions of some library. I've
done a bit of searching but have come up dry.

I'm wondering if any of you other nuts can point out examples?

Thanks,

g.

I’m pretty sure there is no “otherwise simple” example, because depending on two versions of the same library isn’t usually something a project does deliberately (except as a last resort). It’s normally the consequence of an extremely complex forest of dependencies.

It's a hypothetical example but perhaps shows enough of what you're after?
