Remaining problems in SWI-Prolog
* Still, we have to search for a solution to garbage collection
while foreign code is active.
* Read/1 is buggy. Operator resolution still does not solve all problems
correctly.
See:
?- op(900, fy, cd).
cd :- cd ~.
is read as cd (:- cd ~).
* Bagof/setof have a bug as reported by Paul Broome <broome@BRL.MIL>:
The symptons are that variable bindings in subgoals of bagof seem to
be lost. An example that illustrates the problem is the following:
| ?- bagof(Z,(X=Z),L).
L = [G206]
X = G148
Z = G149 ;
The variables G206 and G148 are the same but this fact is lost.
