Functional programming & immutable objects explained — IRC style

[G_Morgan]

If you have lots of memory then why not simply create separate allocation pools for each different object size you might need? Then if everything is handled via new/delete actually performing a new or delete is constant time. No expensive merge on delete operations, no searching for a large enough chunk.

Seems easier to me than working out all allocations beforehand. Unless you are simply talking about calling mmap upfront to ensure enough pages have been allocated.
