Re: Get_Line

Nothing is wrong with it, except that I find it annoying that I must 
have an anonymous inner block to solve the problem.

I think I've gotten an answer to why it is a function; it is a straight 
port of the C-version. But I don't see why a procedure can't be added to 
make the library more comformant with the string IO of standard Ada.
