   Maybe we can have a second argument for this, defaulting to stdin()
   so

   let stuff: String = read!("<b><i>{}</i></b>");

   would be equivalent to

   let stuff: String = read!("<b><i>{}</i></b>", stdin());

   so that we could do

   let stuff: String = read!("<b><i>{}</i></b>", html_input_string);

   sorry, this issue must've gotten lost in my emails... That's a great Idea, I'll address it.

   Doing files is hard... You usually want to continue reading in the file with a new read! call or similar... so right now it looks like

   use std::io::Read;
   let mut file = std::fs::File::open("tests/answer.txt").unwrap().bytes().map(|ch| ch.unwrap());
   let val: i32 = read!("The answer is {}!!!11einself\n", file);
   assert_eq!(val, 42);
   let s: String = read!("There is {} spoon", file);
   assert_eq!(s, "no");

   Which is quite a mouthful for reading from a file.

   Until we get impl specialization, there's not much I can do except add a macro for turning a filename into a bytes iterator to the file.
