Migrated from http://lampsvn.epfl.ch/trac/scala/ticket/1715
The Eclipse plugin relies on JDT's RelevanceSorter for sorting completion proposals. This does not take into account Scala-specific concepts (see comment:3:ticket:1643
and replies for an example). It's not particularly high priority, but it seems like a good idea to implement one that does.
Miles suggested asking the mailing list for opinions on what's the best way.
For future reference, I had a look and RelevanceSorter relies on CompletionProposalComparator for the actual work.
