There are an infinitude of cycles that could be extracted
from this, but we’re only interested in the set of
shortest-length cycles.

Exhibit A:

Exhibit B:

And the classic philosophical gem, Exhibit C:

Is the problem solved, then? Not quite. The current
DebGraph cycle detection operator works well for
dependencies, but we also want to discover cycles of
conflicting packages. Furthermore, one of our documented
use cases involves finding nodes that depend on and
conflict with one another.
