 :	b		binary backward compatibility; function is a macro
 :			but has also Perl_ implementation (which is exported)
 :	U		suppress usage example in autogenerated documentation
+:	a		allocates memory a la malloc/calloc.  Is also "R".
+:	R		Return value must not be ignored.
+:	P		pure function: no effects except the return value;
+:			return value depends only on parms and/or globals
+:
+: Pointer parameters that must not be passed NULLs should be prefixed with NN.
+:
+: Pointer parameters that may be NULL should be prefixed with NULLOK.  This has
+: no effect on output yet.  It's a notation for the maintainers to know "I have
+: defined whether NULL is OK or not" rather than having neither NULL or NULLOK,
+: which is ambiguous.
