By an accident - mixins are not hygienic.

Yes, all the time. Documentation is always lacking and reading 
full 10 MLOC code base to tweak a single function is never an

He has no idea how you may name your variables, that is the key 
point. Thus he has no idea what safe symbol names to use.

You will have a bugged/malicious function in your code base, one 
very easy to detect and fix. Nothing in common with discussed 
problem.
