-* **huge performance boost** - parsing speed is literally half of what it used to be (and it was already fast). The following graph shows parsing speed, **to include** building the parser of valid arguments for a complex scenario with many arguments, relationships, and other restictions was parsed in ~10,000ns (~0.01 miliseconds)
