$(SPEC_S The Memory Safe D Spec,

	$(P $(I Memory Safety) for a program is defined as it being
	impossible for the program to corrupt memory.
	Therefore, the Safe D consists only of programming language
	features that are guaranteed to never result in memory
	corruption.
	)

	$(P Safe D is enabled on a per-module basis by compiling with
	the $(B -safe) compiler switch.
	)

<h3>Proscribed Forms</h3>

$(UL
	$(LI $(LINK2 iasm.html, Inline assembler).
	)

	$(LI Casting away const or immutable attributes.
	)

	$(LI Casting away shared attributes.
	)

	$(LI Casting from one pointer type to another pointer type,
	except for:
	$(UL
		$(LI casting to $(CODE void*) is allowed)
		$(LI casting from a pointer to an arithmetic type to
		a pointer to another arithmetic type of the same or
		smaller size is allowed)
	)
	)

	$(LI Casting from a non-pointer type to a pointer type.
	)
)

	$(P A safe module can import and use the public interface of
	a system module.
	)

<h3>Limitations</h3>

	$(P Safe D does not imply that code is portable, uses only
	sound programming practices, is free of byte order dependencies,
	or other bugs. It is focussed only on eliminating memory corruption
	possibilities.
