  I am interested in some of the problems with 'intensional directories.'
Around here we have used terms like 'expression folders' and 'computed
folders'.

  Some of the questions we have about this which we haven't answered seem
very basic. 

1) Can a user move/drop files into a computed folder?  This would have to
change the expression defining the folder.  If not what is good way IN THE
INTERFACE to make it clear that this is not permitted.

2) Defining a computed folder is a problem.  Files and objects can carry
an enormous amount of info around that would be useful in a computation.
(EG.  Have a computed folder which displays the last five files that I
 changed.)  The language that could manage this seems to be in the realm
of a 3GL ... how can we take a step up from there.

I would be interested in seeing other problems with this idea as well as
solutions which have been found.
