That is what I tried to do in the book.

This was inherited from Smail 3. But nobody has previously objected. :-)

If you think that way, a file that can be linearly searched *is* a file
of a certain type, is it not? :-)

This is just a problem of perception, I'm afraid. Now, I know that in
Unix, a file is a file is a file. So my mental emphasis is on how it is
searched rather than thinking of a file "type". You could try lsearching
a file build by cdb - it probably wouldn't find anything, but it would
be possible. Obviously, your perception is different. This is what makes
communication hard...
