Eglot can handle this and it works pretty good for now:

Open a ex file, enable `eglot`, insert `do` and press `tab`, eglot will
help you insert `end` automatically.

I think it's better to let user trigger `do`'s completion.  Because when
someone want to write a one line function, the `end` is not needed:

```elixir-ts
def foo(a), do: a
```

Anyway, hope to see the new feature ;)

Yes, I think we should add some version of this.  I am currently
testing a
syntax-propertize-function addition to solve an issue related to
electric-pair-mode and will have a look at this straight after.

There was another request to automatically insert `end` when `do`
is
entered, which might be a good addition as well.
