Thank you for your input, Ali! Would it be appropriate to forego 
`readf` and read input as a string using `readln` ,benefiting 
from the `strip` function, then convert to their appropriate 
datatype as in the following example?:

```d
module hello_world;

import std.stdio;
import std.string; // strip()
import std.conv; // to!int(),to!float()

void main() {
	writeln("Hello world from D!");
	write("What is your name? ");
	auto fname = readln.strip;
	writeln("It's so nice to meet you ", fname, "!");
	write("How old are you? ");
	auto age = to!int(readln.strip);
	write("What is your GPA? ");
	auto gpa = to!float(readln.strip);
	writeln("So, ", fname, ", you are ", age, " years old and your 
GPA is ",
		gpa, ".. stellar!");
}
```
Also I signed up with Educative.io to do your interactive D 
language lessons. It really goes so well with your book :)
