At least Perl "uses" `use` for more things than just strict mode. As a beginner, I remember finding this magical literal that (might) alter JS behavior pretty strange, especially since there were no other `use` directives. I really like Perl's `use diagnostics` directive, which provides more verbose error messages, and am frankly surprised a far more popular language that is supposed to be beginner-friendly does not have something similar.
