Jay McCarthy 3cd6be5931 I believe this fixes PR12117. The teaching languages rely on syntax/struct. (I have run the teaching language tests, but do not other uses of syntax/struct.) It appears that syntax/struct has been incorrectly creating this information for some time. The problem is that it would end the static info with a #f if the selectors or setters were omitted, but reading the documentation implies that there should be a final #f in either case. I've therefore changed the boolean to an or over the flags
