FYI, the docs for endian-blob don't indicate the ordering of the endian blob after type->endian_blob. From reading the code it's MSB and there's an optional "mode" arg to these procedures. Should this be documented? Similarly the optional mode argument to byte-blob->endian-blob is documented as being required not optional.
