@eugene-bulkin Hi, do you have time to take a look at this PR? Thanks!

Any update?

You should also bump the MSRV in the CI file.

BTW, I guess we don't need to use a rust jinja.

The feature is conflicted with #114

The real solution is that an SLT file should be both self-contained and easy to use. An example of this is [JsonNet](https://jsonnet.org/). If we don't want to spend too much...

You don't need to fix typo, it'll be fixed in #16663

Is this a good first issue?

Interesting, but I can't explain this phenomenon. IMO this PR should only have an effect on UDF :)
