## 1b. Templating Language

Same as 1, but directly inspired by existing templating languages.
Leverages the familiarity with established templating solutions,
such as [Jinja](https://jinja.palletsprojects.com/en/3.1.x/), [Twig](https://twig.symfony.com), and [Liquid](https://shopify.github.io/liquid/).

```

{% local $foo = $bar :function option=value %}
Hello {{ $var }}, you have a {{ $foo }}

## 2. Text First, but Always Code After Code-Mode

This is @mihnita's proposal, mentioned in the 2023-10-02 call.

## 2a. Text First, Current Syntax for Complex Messages

Starts in text mode,
but switches to the current code-mode syntax
when the message is wrapped in `{{ }}`.

```
Hello world!

Hello {$user}

{{ input {$var :function option=value}
{Hello {$var}}
}}

{{ input {$var :function option=value}
local $foo = {$bar :function option=value}

## 3. Use sigils for code mode

Try to redues the use of `{`/`}` to just expressions and placeholders instead of the three

## 3b. Double sigils for code mode

Same as 3, but the `#` sign is only special when followed by `[`,
hopefully making escaping rarely needed.

Requires `#[` to be escaped in unquoted patterns.

This variant also experiments with dropping the `when` key.

```
#[input $var :function option=value]
Hello {$var}

#[input $var :function option=value]
#[local $foo = $bar :function option=value]
Hello {$var}, you have a {$foo}

## 4. Reducing keywords

Avoids keywords in favor of sigil based parsing.
