Re: [Modules] Get variant of another module

[Xavier D. <xav...@gm...>]

Good to see you found some way!

Using "getVariantList" is not future-proof, especially that this
procedure requires some refactoring.

Please open some issue to have a proper modulefile command to query
variant of loaded modules.

Merry christmas,
Xavier
