In the above example, the build logic uses iteration and mutation to try to set a default version for a particular dependency if the version is not already set.
Build logic like the above example creates challenges in resolving declared dependencies, as reporting tools will display this dependency as if the user declared the version as "2.0", even though they never did.

	// All object storage operations are registered as HTTP handlers on `objectAPIHandlers`.
	// When the handlers get a HTTP request they use the underlying ObjectLayer to perform operations.
	globalObjLayerMutex.Lock()
	globalObjectAPI = objLayer
	globalObjLayerMutex.Unlock()

	// When cache is enabled, Put and Get operations are passed

			// would prefer to use instead of arbitrary versions.
			return true
		}
	}

	// The build list will be the same on the next iteration as it was on this
	// iteration, so any ambiguous queries will remain so. In order to make
	// progress, resolve them arbitrarily but deterministically.
	//
	// If that results in conflicting versions, the user can re-run 'go get'
