Not a good idea. Because if there any mistakes in the config, you would like
to print useful explanatory error messages to help the writer of the config
file figure out what they’ve done wrong, rather than relying on them to
understand Python exception tracebacks. Also your config validation rules
may not map easily to Python language rules.
