See also SRFI 111: Boxes and SRFI 189: Maybe and Either: optional container types.This SRFI extends the specification of the boxes of SRFI 111 so that they are multiple-values aware. Whereas a SRFI 111 box is limited in that it can only box a single value, multiple values can be boxed with this SRFI.
