For the most part, people say you can use leaves in compost. But I've heard
there are some tree droppings you should avoid putting in compost. Anyone
know which ones?

I've never heard of leaves that harm compost. When fully composted (or
completely broken down into leafmold apart from a compost) all leaves
become the same healthy enrichment. But undecayed or half-decayed, the
juglone in walnut leaves can retard the growth of many plants, so it would
not be wise to use fresh-fallen walnut leaves as an uncomposted mulch in
gardens. But they'll be fine once they're coposted, the juglone completely
breaks down.
