This restriction, to a certain extent removes the added convenience of
listing the items in the operand. Another option would be to create a
choose[] filter operation which can be used to append a range of items from
another list to the list being manipulated. Items could be prepended by
using the putfirst[] operator (which would move these items from the tail
to the head of the list.) Makes the behaviour clearer, but does involve two
steps.
filter="[list[mylist]select:3{mytext!!reference}putfirst:3[]]"
This would leave only the remove[] filter with the anomalous syntax --
seems no way around that :-/
