Equally respectful I have to re-disagree ;)
1. "'struct' should know" is not the case. It should just do what it is told,
not trying to be clever.
What if I *want* the above layout? 4 bytes at offset 10. I do not want
'struct' to do something behind the scenes without need.
2. The reference for the 'native' and 'struct' initialization items says: "a
pair (num . cnt) where 'num' is stored in a field of 'cnt' bytes". It says
nothing about an integer.
Let me give an example of a use case. Let's say I want a fast way to store 8
bytes, with a single instruction, in memmory. Why should 'struct' stop me?
(buf Ptr 10
(struct Ptr NIL '(82 . 1) '(8243127052830861157 . 8) 0)
(println (struct Ptr '(B . 10)))
(println (struct Ptr 'S)) )
(82 101 103 101 110 97 120 101 114 0 95 9 88 0 0 0)

I *want* to be able to store an 8-byte value at an offset of 1, if the hardware
allows it.
