My guess is that the code I gave, which honestly is bad because I forgot
about readFile, is probably lazy rather than strict because according to
[0], readFile is lazy despite the fact that it doesn't require explicit

Sorry, looks like I accidently hit r instead of L so it got taken off
the mailing list.

    Look at that--the guts of the program take up only two lines!
    readFile returned a lazy String, which we stored in inpStr. We then
    took that, processed it, and passed it to writeFile for writing. 5
