Compare irb and python:

$ irb
>> ^Dkaye:~ masak$

kaye:~ masak$ python
Python 2.6.1 (r261:67515, Jul 7 2009, 23:51:51)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> ^D
kaye:~ masak$

Irb shows a '^D'. Python does both that and puts in an extra newline
to unclutter things. Python has it right, IMHO.

To provide another interactive shell example (but not a vote):

(I hit ^D after the %)

$ tclsh8.5
% $

I have always preferred the look that masak++ suggests: ^D or ^C or ^Z
(as appropriate) followed by newline. Thus I vote +1, as long as the
correct character can be determined in the current environment. I also
like to see "Received SIGFOO, exiting.\n" for signals that we interpret
as ending the REPL session.

...and now, in 2013, we have neither "^D" nor newline.

Here's my REPL today, first exiting with ^D.

$ perl6
To exit type 'exit' or '^D'

22

Then with exit:

$ perl6
To exit type 'exit' or '^D'
> 3+4
7
> exit
$


I think this meets the criteria of the original request. Closable with tests.
