// Approach:
// 0.When keywords don't conflict, just add both
// 1.Two objects containing $keywords should be merged, following these rules recursively (relevantly, constants override constants, but arrays with $names are merged)
// 2.Arrays with $names should be merged, by appending second array after first
// 3.For two constant values (strings, ints, etc), in the case of a conflict the second value should override the first.
// ^Objects not containing $keywords and arrays without $names should be treated as constants
// 5.When a conflict is not otherwise covered by these rules, just use the second of the two values
// 6.Consider implementing in the future: Between an object containing $keywords and a constant match being provied, pick the constant match
// (because an exact match effectively supercedes all constraints (except maybe mutually conflicting constraints which should axiomatically return nothing...
// but not sure how that should be dealt with anyway? life would be simpler if we had an $eq operator exposed)
