For an example. Anyone is free to use, but I'm not claiming it's
necessarily the best. This is from... well, probably not yesterday like I
said in other comment, but a couple days ago. The module `jsonschema` has
an API where it raises an exception if `validate()` doesn't succeed (None
if things are happy). I don't love that API, so want to wrap it.
def not_valid(instance, schema):
try:
return validate(instance, schema)
except ValidationError as err:
return str(err)
I really wanted that to be one line rather than a helper function, and it
really feels like it should be possible... and yet.

become abortifacients against new conceptions.
