## std.mem: Unsafe functions for working with raw memory.
## Raw pointers. Extremely unsafe.
## While they are removed from the memory model by default (and hence can
## cause undefined behavior), pointers must know what *type* they point at.
## This cuts down on errors somewhat - not much, but somewhat.
pub type ptr[T] =
addr: uint
## Heap-allocated, memory-safe references.
pub type ref[T]
pub type unique[T]
## Sets the sizeof(T) bytes following data + offset * sizeof(T) to T.
## Extremely unsafe.
pub func raw_set[T](data: ptr[T], val: T, offset: uint = 0) =

## Gets the value at data + offset * sizeof(T), and interprets it as type T.
