Antoine Leblanc 553ecf628b Prevent impure errors with monadic map union ... ### Description This very small PR introduces `unionWithM`, to allow hashmap union that might fail, and uses it to transform an `error` into a `throw500`. It also reorders `HashMap.Strict.Extended` to group all "union" functions together. There is, however, a broader question of whether we should encourage the proliferation of such functions. If so, we might also want to consider: - `mapWithKeyM`, to remove the `unsafeMkName` of `RemoteJoin.Collect` - `forWithKey`, as a flipped version of `traverseWithKey` PR-URL: https://github.com/hasura/graphql-engine-mono/pull/3917 GitOrigin-RevId: a488d5bf04a73878b9e42f27ede36199bb4c920a		2022-03-09 23:27:13 +00:00
