Macros
#define	MF_LIVE_EXPOSE(key, ptr)   ((void)0)
	Exposes ptr to the live arena under a user-supplied key when MAYAFLUX_LIVE is defined.
#define	MF_LIVE_EXPOSE_AUTO(ptr)   ((void)0)
	Auto-expose variant that deduces the key prefix from the shared_ptr element type.
#define	MF_LIVE_EXPOSE_NAMED(name, ptr)   ((void)0)
	Auto-expose variant with an explicit name prefix and per-name counter.
#define	MF_PRETTY_FUNCTION   __PRETTY_FUNCTION__

Functions
