See documentation page for details.

0.5.0 - First public version

• Validate both type and value with isinstance, thanks to easy-to-write "validating types"
• has_valid_type and has_valid_value methods provided for easy auditing, as well as is_vtype
• Validation syntax fully compliant with valid8. Compliant error message available through a validate() method
• v-types are composable so that creating a library of reusable elements is straightforward (note: should we provide one in this library based on valid8 library ?)
• Two styles: vtype(...) constructor method, as well as an alternate class ...(VType) style to perform composition using inheritance, and write docstrings more easily.
