For instance, in Java ...
tmpString = JOptionPane.showInputDialog("What is your foobar?");
finalFoo = Double.parseDouble(tmpString);
instead of ...
finalFoo = Double.parseDouble(JOptionPane.showInputDialog("What is
your foobar?"));
I translate this into Clojure as something like ...
(def final-foo
(. Double parseDouble
(. javax.swing.JOptionPane showInputDialog "What is your foobar?")))
Obviously this a contrived example, and I didn't compile it to make
sure it works. Still, you can easily imagine more complex code having
many more levels of indentation.
How would I break up the Clojure version in a Clojure-esque manner?
