Review comment:
thanks for taking a look @kgyrtkirk! there are examples in exception_in_vertex_udf.q, do you think it's enough to mention it here?

Review comment:
I was thinking to add some notes about it to the `@Description` - I would look there first in an UDF

Review comment:
I know it will be mostly just us using this - but it would be helpfull to document the accepted format (and probably throw an exception if something else is passed)
