I've written GUIs and other reactive systems with Hugs and GHC which did not leak space and, since the bulk of the work was done by X or Win32 (i.e., standard library code written in C), ran fast enough to keep up with humans. I doubt that GHC's speed and optimizations will fix your problems. > As I see it the problem is basically that of tail recursion removal > or as David Bergman calls it "last call optimisation". I suspect this may be a red herring. Space leaks in Haskell are most often caused by hanging onto unevaluated expressions or by accidentally hanging onto data that should be garbage. You should use a heap profiler to identify the true cause of your space leaks and then go fix those. GHC and NHC both contain good heap profilers. GHC contains libraries that are most similar to Hugs. -- Alastair Reid [EMAIL PROTECTED] Reid Consulting (UK) Limited http://www.reid-consulting-uk.ltd.uk/alastair/ _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
