Reference variables inside custom error messages

[atheiman]

Need the ability to reference variables in custom error messages. It makes the guard code cleaner when you can check for a value, then raise a custom error for that value missing. Im trying to use this for Config rule evaluation annotations, and the Config docs show this is not supported.

Note: Currently, Guard doesn't support referencing variables inside custom error messages.

Hi @atheiman thanks for the enhancement idea.

This is definitely something we will consider moving forward. We will update this ticket on this matter as necessary.

Thanks,
