# Description
Generally elide a bunch of unnecessary clones. Both globally stopping to
clone the whole input data in a bunch of places where we need to read it
but also some minor places where we currently cloned.
As part of that, we can make the overwriting with `keep-all` and
`keep-last` inplace so the items don't need to be removed and repushed
to the record.
# Benchmarking
```nu
timeit { scope commands | transpose -r }
```
Before ~24 ms now just ~5 ms
# User-Facing Changes
This can change the order of apperance in the transposed record with
`--keep-last`/`--keep-all`. Now the
order is determined by the first appearance and not by the last
appearance in the ingoing columns.
This mirrors the behavior when not passed `keep-all` or `keep-last`.
# Tests + Formatting
Sadly the `transpose` command is so far undertested for more complex
operations.
