[Modules] set-alias when module load in interactive, but 'unalias: foo: not found' when unload in non-interactive

[Myles <smp...@gm...>]

I have a module with a set-alias that I load for my interactive shell.
Let's say the alias is 'foo'.

Then, when I run this script from that interactive environment:
#!/bin/bash
module purge

I am getting:
environment: line 26: unalias: foo: not found

This is because the alias is not propagated to the child process. Shouldn't
the unalias that happens during an unload check that the context shell is
interactive?

I am using EnvModules v5.3.1.

I found this discussion, but I couldn't decide what to take away from it.
