Cycles in Fields

Also, we know that unifying a field with itself will result in the same value. Thus if we have a cycle between some fields, all we need to do is ignore the cycle and unify their values once to achieve the same result as merging them ad infinitum.

cycleref.cue:

labels: selectors
labels: {app: "foo"}

selectors: labels
selectors: {name: "bar"}

$ cue eval cycleref.cue

labels: {
    name: "bar"
    app:  "foo"
}
selectors: {
    name: "bar"
    app:  "foo"
}
