Hygiene issue detected by JET.jl

[MilesCranmer]

Just a heads up (no MWE) some JET issues in my package led back to MacroTools. This might just be an issue in Base but I thought I'd share in case you recognize any potential issues from it:

Yeah, see also #159. Now that JET is well established, I would be happy to merge a PR fixing these issues.
