And catch the exception to abort and print a readable warning?

Just reraise it as copier.config.objects.UserMessageError and it should be enough.

Otherwise, an exception would be acceptable for what you said before.

Oh silly me. In strict mode, if the string cannot be rendered (due to variables not being defined or else), it will trigger an exception. That’s how we’ll know. For some reason when writing this I was thinking that, if the string couldn’t be rendered, it would be returned as-is, but it’s not true. Instead it would be returned empty (or partially empty), and that would be hard to detect.

Strict mode it is! And catch the exception to abort and print a readable warning?
