IEx Pry: Always allow / take over without prompt

Question

When I run Elixir code with my debugger, Pry, then it always confronts me with Allow? [Yn]

1. Can I pass a configuration option to always allow this? Thus, by default?
2. Why is this question asked? What could be harmful?

Answer 1

No, you cannot provide an option to allow without manual confirmation.

The confirmation is a reused component of IEx, any terminal takeover messages (:take) require user confirmation. This take over flow also happens in IEx.pry/0.

As for why this is the case, I am not sure. I would assume it is a security measure. However, the confirmation simply safeguards IEx.evaluator.run/4, which does not seem to be an obvious attack vector.
