This makes it very difficult to read values. We can't retire din.readf before
fixing this.

import std.stdio;

void main()
{
    int i, j;
    readf("%s", &i);
    readf("%s", &j);
}

Run the program and provide the following as input:

42 43

The program terminates with

std.conv.ConvError: std.conv(1070): Can't convert value
`LockingTextReader(File(807637C),  )' of type LockingTextReader to type int

The reason is the white space.
