Unboxed Types for OCaml
OCaml has a well-deserved reputation for compiling quickly. This is thanks in part to its uniform representation: all values have the same memory layout, so generic code does not need to be specialized and recompiled for each use.
This uniformity has a downside: some programs waste a lot of time converting back and forth to this uniform representation.
In this talk, I'll describe some work-in-progress to remove this overhead, by extending OCaml's type system to allow other memory layouts, giving the programmer more fine-grained control over how code is compiled.
