It doesn't seem to be the liberty frontend proper (invoked by read_liberty
) that spouts the message, rather it must have been the liberty parsing in dfflibmap
. That code doesn't seem to support expressions at all (other than simple negation), and it failed to detect it's being supplied one, so it didn't print out a more helpful error message.
