…#23537) * Improve description of 'e', 'f' and 'g' presentation types * Drop the 'E' from Scientific 'E' notation; remove >= 0 qualifications * Fix false statement that the alternate form is valid for Decimal * Nitpick: remove the Harvard/Oxford comma * Add note that the decimal point is also removed if no digits follow it, except in alternate form
bpo-42202: Store func annotations as a tuple (GH-23316)
Reduce memory footprint and improve performance of loading modules having many func annotations.
>>> sys.getsizeof({"a":"int","b":"int","return":"int"})
232
>>> sys.getsizeof(("a","int","b","int","return","int"))
88
The tuple is converted into dict on the fly when `func.__annotations__` is accessed first.
