Apologies for derailing the thread, but I had a similar problem a few
months ago [*], found what looks like a different solution but did not
have time to investigate it further.

Given that serialize() does not send package namespaces over the wire
[**], why would it be a bad idea to pass actual functions (instead of
character strings naming functions) to parallel::parLapply and friends?
This seems to avoid the need to export the worker functions or use :::
in calls to parallel functions from package functions. Unless I am
missing something, which I probably am.
