they likely are referring to how import mechanisms in other languages operate outside the scope of imperative execution, like Perl's "use" statement, or in the way that a compiled language like Java handles imports. It is exactly the vast confusion that Perl's "use" caused me, even after I used Perl in a professional setting for almost ten years, that allowed Python's "first class object" approach to imports to be one of the most liberating breaths of fresh air I've ever had in my programming career. Of course, imports being imperatively executed causes the nasty problem of import dependency cycles in code but it doesn't even bother me.
