A Mathematician looks at D

[Joshua Niehus]

Personally I find REPLs super annoying, especially when you need 
to "import" or "require" something or like to use multiple lines. 
  Serious how hard is it to just do:

### Ruby
#!/usr/bin/ruby
require "pp"

puts "do stuff"

// D
#!/usr/bin/rdmd
import std.stdio;

void main() {
     writeln("do stuff");
}

then press "Command+b" (Sublime text) and watch it work/fail?
