[kgryte]

This is entirely incorrect. You misunderstood the issue. Our REPL environment uses the project's global namespace. Here, you are just checking for JavaScript globals. That is incorrect.

[headlessNode]

@kgryte should the rule only check exact matches against entries in the aliases list (i.e., non-dotted aliases like abs, acartesianPower), or should it also flag variables matching namespace prefixes like base, random, strided, and fastmath (the first segment of dotted aliases like base.abs)?

[kgryte]

Given that base, random, etc are reserved aliases (i.e., they are in the global namespace and we should not be overwriting them), I believe the answer should be self-evident.
