PEP 570 (Positional-Only Parameters) Got Accepted
This PEP introduces a new syntax, /, for specifying positional-only parameters in Python function definitions. Looks useful for getting tighter control over how a library API can be called (i.e. preventing positional params from being called as keyword arguments). This will also allow for some function call speed optimizations in the future.
