That looks useful for binary data. I don't see from the code how to use
it to save and load a hashtable. The spec format supports these types:
;; TYPE ::= ( eval EXPR ) -- interpret result as TYPE
;; | u8 | byte -- length 1
;; | u16 | word | short -- length 2, network byte order
;; | u24 -- 3-byte value
;; | u32 | dword | long -- length 4, network byte order
;; | u16r | u24r | u32r -- little endian byte order.
;; | str LEN -- LEN byte string
;; | strz LEN -- LEN byte (zero-terminated) string
;; | vec LEN [TYPE] -- vector of LEN items of TYPE
(default: u8)
;; | ip -- 4 byte vector
;; | bits LEN -- List with bits set in LEN bytes.
Is there some magic with `eval'? I didn't get it.
In addition, this library doesn't manage file I/O. I'd expect the
library do do content coding and error handling internally. This is,
actually, the most tedious part. Transforming a hashtable to a list and
back is easy (even I can write it :)
