If I remember the implicit finalization system may be slower (probably a good idea to test instead of trusting my word on this). WITH-* style macros are also a very common lispy interface, require very few indentation and permit explicit, immediate finalization as an option. - Alternatively, instead of full finalization+delete/free in WITH-*/GC, objects could potentially be finalized then cached as slab allocators do; this will help if objects are complex and part of the instanciation+initialization can be preserved. -- Matt ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
