To my mind, a 4:1 reduction in boilerplate lines, moving the function
name out to the top level, making it clear that there's only one
function (the inner one) that is kept around, avoiding repetition of
the variable name and the function name all count as fairly
substantial wins on the 'sugary goodness' front :)
