I believe that reading a string from console should be considered one of
the simplest task to perform.....
Ok i do not pretend a sintax like
s1 = input()
ala Python but perhaps somehting like
string s1 = Console.Readline();
as in C# mode would be sufficient for a basic input control... sure, it's
more readable... but actually the thing that puzzles me is that you cannot
write something like:
let mut s1 = stdin.read_line();
cause the compiler complains (why?)....it's a matter of taste, of course.
