Feature or enhancement

Proposal:

It's possible that the file is modified during debugging, which would definitely confuse users - the source will not match the execution anymore.

There's no perfect solution under such circunstances, but we should at least warn users that this is happening.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
