I think we were waiting on Rob to change this into a pull request. Not sure if
that's going to happen?

I'm planning on putting in a pull request for this, probably sometime over the

I did some benchmarks with this and some other variants.
At least for small strings, this code performs worse than the current appender.
Judging by the description it's optimi

I did some more digging. I reworked the put routine itself and changed the
growth strategy to be as aggressive as the original appender. This got me down

I spent some more time working on an optimized appender. Things I found:
1) Extra indirection levels are performance killers
2) I failed to create a chained appender (like th

My code is more of a research project. It can't be safely copied, only supports
items 1 byte in size, and doesn't care much in terms of UTF encoding. So, it
can't be a drop-in
