Slash notation should be defined in a notation key at the beginning of the Built-In Functions section

Documentation

The Standard Library defines a number of built-in functions, and a shorthand notation is used when a function is defined, such as the definition of repr:

repr(object, /)

But there is no information about what that "/' means in the function signature. It is not standard computer science notation, so I started looking for its meaning. Normally, a notation key should be at the beginning of the document or section, but I do not find a notation key either at the beginning of the section or at the beginning of the documentation.

Could a notation key be added please, to define the meaning of this and any other non-standard notation that is used in the Python documentation?

Start at the Built-in Functions section of the Python Standard Library documentation and review the function-signature notation around repr(object, /). Add a notation key explaining the slash and any other non-standard notation identified there; the documentation is done when readers can understand these signatures without searching elsewhere.
