I agree, and appreciate your efforts to improve link handling in 3.15. I have
often wished link handling were more orthogonal. In one of my self-written
record types I once had code that called recGblInitConstantLink at runtime
(each time the record was processed) because that really simplified the code
(I could save a number of record fields to store the constant value and could
avoid case distinctions). However, in practice it was too slow, so I had to
revert back to the standard method of using recGblInitConstantLink only in
init_record.
