[PEAK] How do I extract a subset?

[Peter Damoc]

Hello,

I have an app where I use a trellis.Set to hold some records, a
trellis.SortedSet to keep them in order but now I need to filter the records
based on some criteria.

records = trellis.Set()
filtered_records = trellis.???
sorted_records = trellis.SortedSet(data=filtered_records)

How can I do this?

Also, if I have an observer that watches over sorted_records, shouldn't it
be triggered if a change in the  underlying set is made?

Peter
