F# is .NET, so you can have pretty fine grained control over memory layout, right? Spans, packed structs, 8/16/32/64 bit signed/unsigned ints, etc. That stuff

F# is .NET, so you can have pretty fine grained control over memory layout, right? Spans, packed structs, 8/16/32/64 bit signed/unsigned ints, etc. That stuff all gets a bit screwy in Ocaml, an int has 31 bits of information but is 32 bits in size, a record with two int 64s ends up being twice you expect, etc.
