Of course, defining the function makes it easier to invoke your code if you

Hi Keith,
IMO it is slightly better to use a function as you described. The
benefit being that it makes it easier to test your helper functions
without running the main application. For instance if you comment out
(main) and load the file to the REPL or call a test function instead.
It seems the

And one more added benefit is that if you (or something using your

time they are saved (such as clojuredev does), it would be impractical to
have a namespace auto-execute itself. Because then, the auto-load

Hi all,
when experimenting at the SLIME REPL it often happens to me that I eval
an expression which runs very long (or infinitively). This may be
intended, like to prove that (some #(= 12 %) primes) will run forever

The question is: How do I abort such an evaluation? Currently I do
