Research direction
Start by locating the existing validator entry points and reviewing how validators signal invalid values. Define the expected behavior for wrapping a boolean-returning function, including its invalid-value error, and confirm the validator API and documentation consistently describe the new option.
Written by the indexing model from the issue text.
Description
Currently, validators are required to raise an exception, if the value isn't appropriate. If I currently have a function for checking the property, but returns a boolean, instead of raising, to use it as a validator, I have to write a wrapper that converts the return to an exception. It would be nice if attrs provided such a wrapper itself.
