Linker errors when building with --xcode-integ on Big Sur

I'm running into build errors on Big Sur when using cargo-lipo in an Xcode build script. I've made a small test project [here](https://github.com/irh/rust-big-sur-test/tree/60c44b67e4bc4a64cc0d00d7014b31390bac639e). It builds successfully in Xcode 12.2 on...

It would be useful to have an `eval` style feature in Koto. There are lots of use cases to consider, but I think a meaningful starting point could be achieved...

It would be useful to be able to define [function objects](https://en.wikipedia.org/wiki/Function_object) in Koto. This could be achieved by adding a `@||` meta key that can be defined in `Map`s, which...

Optimize tail calls

Currently no effort is made in Koto to optimize tail calls, making it easy to run into stack overflows when implementing recursive functions. e.g. The following script takes a huge...

The `wasm` CI job checks that the Koto library compiles on CI but it doesn't run any tests, it would be good to run at least one test with the...

It would be good to have an `iterator.reversed()` function that reverses the direction of any iterator that can support being reversed.

Currently the parser discards comments and whitespace when parsing a script. Tools like auto-formatters need to know about these non-semantic aspects of the script (I'll call them 'extras') and their...
