5e08028fb3 Syntax functions 🚀
This adds overridable functions that markup desugars into. Specifically:
- \ desugars into linebreak
- Two newlines desugar into parbreak
- * desugars into strong
- _ desugars into emph
- = .. desugars into heading
- `..` desugars into raw

c94a18833f Closures and function definitions 🚀
Supports:
- Closure syntax: `(x, y) => z`
- Shorthand for a single argument: `x => y`
- Function syntax: `let f(x) = y`
- Capturing of variables from the environment
- Error messages for too few / many passed arguments

Does not support:
- Named arguments
- Variadic arguments with `..`

1c40dc42e7 Dynamic values, Types, Arrays, and Dictionaries 🚀
- Identifiers are now evaluated as variables instead of being plain values
- Constants like `left` or `bold` are stored as dynamic values containing the respective rust types
- We now distinguish between arrays and dictionaries to make things more intuitive (at the cost of a bit more complex parsing)
- Spans were removed from collections (arrays, dictionaries), function arguments still have spans for the top-level values to enable good diagnostics

6bbedeaa2c Better tokenization testing 🌋
- Better tokenization test coverage.

- Improves expression parsing (fixes #3).
