|> less fragile interface to the sub
We showed that any call-by-reference can be affected.
So you are effectively saying that modifying $_[ ] is a fragile interface and bad coding practice?
I agree it's not a crisis, but this must at least be documented, not only for helping people desperately trying to understand the reason why an imported sub using another imported sub fails out of a sudden, because an alias was passed thru the chain.
This can't be avoided, even less if people use Data::Alias or Lexical::Alias.

And how do you expect eval to help if there is no error thrown?
