Following on from keep_oks/keep_errs (#10240), I'd like to take the fallible-threading trio from #9596: List.map_try, List.keep_if_try, List.fold_try (plus their ! variants) — thread a Try-returning function over a list, short-circuiting on the first Err. Pure Roc, modelled on map/keep_if/fold with ?; one PR, one commit per pair. Anyone already on these?
Opened this as #10269, ready for review whenever someone has a moment. :folded_hands:
