I've never heard anyone express that sentiment before. If anything the
opposite is true.
A large part of writing secure code is about avoiding errors, so any
language feature that helps you write error-free code is good for security.

Also, don't forget that vectors are zero indexed, so (- (count v) 1) will
give you the last element, not the second last.

Roelof,
The whole point of something like 4clojure is for you to try to understand
how things work and learn how to fix the errors that happen along the way.
Open a repl and see what the error tells you. Also, you should have the
clojure cheat sheet open to help you find what each function

(= (__ [[1 2] [3 4]]) [1 2])
I tried already the nth but I was also failing on the first. I think
because of count because you cannot know how many values you have.
Remember that indexes work from zero. So if you have a collection of 3
elements:
(nth [a b c] 2) = c
(nth [a b c] 1) = b
(nth [a b c] 0) = a
I'd encourage you to open a REPL and try the solution you have to see what
you get if you get stuck. Often some experimentation will show

I'm no expert, but the arguments I have seen against Swing are
almost always about the API, so they do not really apply to seesaw.
The other arguments were about the non-native look, but I seem to remember

I also think that it's usually better to have a standalone Clojure app
