I see what's going on here. Ruby with no args reads from the standard input
(in this case the terminal) and runs whatever it gets as soon as the input
stream terminates, which is the "^D", and not your enter key. If you were t=
o
use this technique, you would have to tye "ruby" again to execute something
else.

IRB executes and the enter key and then waits for another line to execute.
This is, obviously, much more convenient! :-)
