I never used emacs but in some videos I sah people doing cool stuff in

already better then any IDE I have used. It makes working with the

You mention one use case of the repl, but I think that's just one part
of a typical workflow. Say you decide to write a function, you start
half way and then you realize that you need to group pairs of items in
a vector and then turn these pairs into a vector of maps. Oh, but
what order are the

The confusion over type and instance was a sloppy example. Sorry.
But in your solution I'm confused by one thing. You create and
instance of Foo in the let and then assoc the new value of List1 to
it.
This has two problems. One is that the loaded data is not
permanent. The other is that
Maybe SPOJ treat clojure as script language. In fact, though clojure
is quite fast, loading the clojure.jar library takes a bit of time.
And SPOJ count the class loading time into the running time. If the
Judge Machine is similar to ideone.com, maybe the clojure.jar loading
time is about 0.6~0.7s.

It seem to me there should be some way to load a record at run time
without breaking the immutability laws. Once the dynamic data is
loaded, the record becomes immutable and will never be changed
again.
Actually, that's how records work and is exactly the behavior of the
initial (foo. nil

Todays' project involved modelling what happens if an infected flea

If you go by degrees and shades of synonymity, it can (and has been)
done manually - see Visual Thesaurus (http://

But for grouping based on the same semantic topics - that's pretty
