computedfields are incompatible with F expressions:
should be mentioned in the docs somewhere
fast_update is also incompatible, as VALUES are not allowed to take column refs directly. They can, thx to relational algebra, take a subquery resolving to the needed value, but that leads to very cumbersome lookups with much worse perf than bulk_update in the first place, so nothing to be gained here.
Edit:
fast_update should at least spot F expressions in values and bail out to bulk_update, so we dont break with bulk_update interface.
