I was contemplating how much functionality I could borrow from seg to build another interval type and what unforeseen
hurdleswould emerge while I was digging into it. It turned out to be less straightforward than I thought.

Thank you Michael. I will summarize the problems I have already encountered in a later reply to this thread.

I do find the API to be unchanged, but I get the sense that some macros are new. Maybe it’s just my bad memory.
Overall,I am pleased with a much better automation of extension building and testing.
