I think it has to be done, otherwise that'd just make field permissions
useless.

Ah yes, I forgot that.

I had in mind just bitwise copying them. But I guess that slightly
defeats the purpos
Hi,
Good idea.

That's not possible: `struct-copy' must check fields permission and type
before copying. For instance, `s' fields must be updated, and a struct
with `o' fields cannot be copie
This is an idea I had for copying structures, mainly to make a
`record-copy' function (just an alias of struct-copy). I've found it
pretty useful.
You can do a record copy with `record-constructor' and a map over
`record-accessor' for each field, but of course a block copy is heaps
more efficient
