Wouldn't it surprise rustaceans used to immutable by default variables?

Still, with introduction mutability inside templates it could lead to bugs. E.g. let's say we have this structure: ```jinja # base.html {{ let foo = 100 }} {% include "inner.html"...

Sure, it's just one more handler, it won't interfere into other handlers behaviour

The docs example will do: https://docs.rs/once_cell/1.8.0/once_cell/index.html#safe-initialization-of-global-data A call of `Logger::global()` before `INSTANCE.set(..)` will panic.

Do you mean passing the reference as an argument? I thought the whole point of `once_cell` is having "globals". With passing through arguments why not just initialize the logger and...

Have you considered some sequences like: 1. `V` - enable cell selection mode (i think it's pretty intuitive vim row = jupyter cell) 1. `j .. k` - select some...

I'm really missing cell-level commands too. I agree with @stsievert it's better them to be consistent with vim row-level bindings (at least by default). We're already using this bindings working...

3. I personally would be completely satisfied with `yy`, `dd`, `y` add `d` with selected cells and `p` 4. Sorry, I meant just `ctrl-[`
