If I were developing a compiler, it would be nice to have (perhaps
provided by an add-on?) a side-by-side view of the true source, and the
(JavaScript) object code I generated from it.

One could even make a web page that accepts a script URL, fetches the
script, fetches any sourcemaps that refers to, fetches the original
files the source maps cite, and then plots it all up nicely.
