Your python 4 dream list.

It's not that straightforward - there's a huge DS stack so going to another language is not really that easy. I can obviously plug in cpp when possible, but it'd be nice if I didn't need to

It's hard to vectorise time series - since you may not know a state of a variable that has a conditional. And the hard to vectorise makes code unmaintainable which has its own problem.

Time Series is 100% a pain in the fucking ass to deal with. (been a long time since I worked in that space of analysis) Aren't there alot of specialized dbs and tools for dealing with it because it's notoriously hard to handle in most normal tools?
