Updates that occur in one branch are propagated to the other. In this example, Alice updates foo, while Bob adds a new dependent bar of the original foo. When Bob's branch is merged into Alice's, her update to foo is propagated to his bar.
.> project.create-empty project
project/main> builtins.mergeio
Original branch:
foo : Text
foo = "old foo"
project/main> add
project/main> branch alice
Alice's updates:
foo : Text
foo = "new foo"
project/alice> update
project/main> branch bob
Bob's adds:
bar : Text
bar = foo ++ " - " ++ foo
project/bob> display bar
project/bob> add
Merge result:
project/alice> merge /bob
project/alice> view foo bar
project/alice> display bar
.> project.delete project
