// when we have to dupe a set of peer dependencies deeper into the tree in
|
|
// order to make room for a dep that would otherwise conflict, we use
|
|
// this to get the set of all deps that have to be checked to ensure
|
|
// nothing is locking them into the current location.
|
|
//
|
|
// this is different in its semantics from an "optional set" (ie, the nodes
|
|
// that should be removed if an optional dep fails), because in this case,
|
|
// we specifically intend to include deps in the peer set that have
|
|
// dependants outside the set.
