Do we have a per-file marker mechanism?

The problem with handling case-sensitivity this way is that you want
to close calls to READ over the sensitivity at the call site.  (I found this out
when PLT scheme switched to case-sensitive.  I went and added the magic
# syntax to my files and discovered that it didn't fix the problem.  Calls to
read were being case-sensitive.  It occurred to me that if I'm writing
code, I probably want READ to be insensitive, too. (or if it was legacy code,
that I'd be expecting the old behavior).
