asdf which -a

[nmccamish]

Is your feature request related to a problem? Please describe

If multiple versions have the same tool installed (or tools with the same name), you can only see the path to the executable installed in the current version.

Describe the proposed solution

I would like a feature similar to Unix's which -a, where it would "print all matching pathnames," but for all versions.

Describe similar asdf features and why they are not sufficient

asdf which is good enough, if there only is one version of some tool installed.

Describe other workarounds you've considered

Iterating through asdf list, executing asdf shell, then asdf which for each version.
