The issue is that if there's an error, the bad input doesn't get consumed.
You have to remember to call Skip_Line, so you might as well call Get_Line
instead.

The other benefit is that you can interpret the input as meta-symbols.  For
example, I often interrogate the input as a string first:

"quit"
"q"
"exit"
"x"
"first"
"last"

and if none of these test true, then I go ahead an interpret it as an
integer input.
