Have fun.

This one is more simple. This is clojure code. And the example shows what
unnecessary boilerplate is required in Java which Clojure hides from you.
Everyone knowing how to call a clojure function understands this code after
learning how to get a Var from a namespace and how to to invoke it.
And most importantly: it works. Also for the x above. Just like that. Nothing
more involved.
For yours you have to know what x is. You have to quote it if you want to pass
it as a string. You have to escape various quotes in strings. You have to know
features of the reader.

Compactness says close to nothing about simplicity.
