I confess I did not have a concrete plan, I was just mucking around.  I 
had a "/path/to/a/FILE.ext", and I had to pull out just the "FILE" part 
[1], and I thought, gee, I bet MIT Scheme has string stuff I could use.

Well, it worked, but after I did it, I realized I probably had to pull 
over more MIT Scheme than I strictly needed, and Java has String 
search/index functions already, and I could have done it that way.  In 
fact, over lunch today I was telling a colleague I should time my FILE 
extraction with the code I've got, and compare it against doing it with 
Java String methods.
