Let us motivate the value of augmentations by starting with the following example. Suppose that we would like a function to wrap a string with a left and right string. We could do that in Golo as follows:

function wrap = |left, str, right| -> left + str + right

# (...)
let str = wrap("(", "foo", ")")
println(str) # prints "(abc)"

Defining functions for such tasks makes perfect sense, but what if we could just add the wrap method to all instances of java.lang.String instead?
