That's true, Bill.

I frequently have rules in my fuzzy models like:

if costs[t-N] are much greater than income[t-(n+1)]
then margins are reduced;

(where "margins" is a time series variable and is assumed to be "margins[t]").
Few, if any, control fuzzy shells can encode this kind of rule. I also have
rules like,

for each project where cost are high and duration is long;
if project.revisions are large
and diff(&today,project.duedate) is a LargeNegative
then risk is very high;

where the rule can incorporate database or spread sheet access. Again, the
fuzzy control shells usuallyhave no way to access corporate data.

Thus, re-entrant and recursive rules are just one problem with the current
family of fuzzy shells.
