Getting values from other Datapoints in Groovy ComplexDatapoint

Just now, Stuart Weenig said:

For Groovy based datapoints, when SNMP is the collector, there is a variable set in the script called "output". You can parse through that output variable to get the data. If it's counters, you'd need to use collector script caching to get the previous poll value to run the delta manually.

We were already doing that. However, we wanted values from other datapoints (gauge, derive, etc...).... Which as per the documentation isn't possible (validated on Friday)
