Who's talking about *entering* it into the program at a keyboard
directly, though? Input to a program can come from all kinds of crazy
sources. Just because it wasn't typed by the person at the keyboard
using this program doesn't stop it being input to the program.
A concrete example, but certainly not the only possible case: non-ASCII
digit characters representing integers, stored as text in a file.
Note that I'm not saying this is common. Nor am I saying it's a
desirable situation. I'm saying it is a feasible use case, to be
dismissed only if there is strong evidence that it's not used by
existing Python code.
