Drat, now I'm gonna be up at odd hours tonight dredging my brain 
for such corner cases.  My catalog so far:

- triple-quoted multi-line strings

- "\" line-continuations don't work with trailing whitespace 
(though Vim's syntax highlighting flags them, changing their 
color if there's whitespace afterwards)

- files that read themselves (or perhaps depend on 
introspection/debugging modules to read themselves)

Any others that I missed?
