If you figure or any alternative to datomic, @tbrooke, let us know, please.

@tony.kay: yep :)… btw, any idea about using recursive queries cleanly? By default it appears to leave dangling unordered lists...

what do you mean dangling?

the order is defined by the data

i think he’s referring to https://clojurians.slack.com/files/folcon/F0V6ZM7V4/without-tweaks.png

yes, sorry

my solution was to modify the defui Person adding a predicate to test that the person/mate was the correct shape, just wondering if there’s anything more elegant ...

@folcon: not that I can think of...you have to do something to detect the loop, and the behavior of db->tree is to return an ident when it hits something it has already seen.

In non-loop cases (much more common) you'd just get nil, which is easier to pun into shape (when mate ...)

thanks, I’ll have to think about it some more and see what works over time ...
