I was curious, so I checked. I didn't see anything specifically referring to builtins. This is as close as it gets:

"If a function argument's name clashes with a reserved keyword, it is generally better to append a single trailing underscore rather than use an abbreviation or spelling corruption.  Thus "print_" is better than "prnt".  (Perhaps better is to avoid such clashes by using a synonym.)"
