Re: [Modules] Get variant of another module

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

The "is-loading" procedure exists but is not currently exposed in the
modulefile evaluation context. You may try to expose it with
"modulefile_extra_cmds" hook variable and see if it cope with your use
case.

The variant propagation method is a good one also. But I feel with
your message that the "goat" module is not compiler-specific so it may
not be semantically correct to have a compiler variant?

Best regards,
Xavier
