I feel very strongly that users debugging their sources that were

My experience with debuggers says the while the vast majority of the time you want to be able to debug it in the language you wrote, sometimes you want to debug it in the language it broke in. Being able to look at the lower level language can clear up misconceptions about what a higher level construct means. It can also reveal compiler bugs.

It should also be recognized that all compiled programs break in machine language. :-)
