Intuitive instruction order

[algesten]

It could be argued that the following order is "more intuitive" since set/merge operations would have indexes that are true for the original array being modified.

1. Merge
2. Set
3. Insert
4. Delete

This way only the last delete instructions may be affected by previous inserts. The current way all instructions are affected since deletions are done first.
