Python 3.10's new features: Parameter specification variables

The video tutorial introduces a new feature in Python 3.10 called parameter specification variables, which enhance the type hinting system. It explains how decorators can obscure type information and how Param spec can solve this by forwarding parameter types from one function to another. The tutorial provides examples of using Param spec to maintain type integrity in decorated functions, ensuring that linters can detect type mismatches before runtime.
