@alamb , I agree with you that we will need to migrate to a visitor pattern. The goal of this PR is to write functions that walk and re-write the tree, so that we do not have to copy-paste stuff when writing an optimizer. This will make it easier to migrate, since there is well defined pattern in place to migrate from. @andygrove and @alamb , I rebased this against master again. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
