But it can be done while processing a node list: replace sequences of nodes (e.g. two hyphen nodes) by something else (an en-dash). That's basically how contextual ligatures are implemented (and even simple ligatures when luaotfload is in "node" mode, if I remember correctly), so it's no big deal.

Taco once told me that this way of avoiding ligatures, advertised as a 
feature, was actually a nasty side effect and was removed on purpose.
