### Runes
A `rune` represents a unicode character and is an alias for `u32`. Runes can be created like this:
```v
x := `🚀`
```
A string can be converted to runes by the `.runes()` method.
```v
hello := 'Hello World 👋'
hello_runes := hello.runes() // [`H`, `e`, `l`, `l`, `o`, ` `, `W`, `o`, `r`, `l`, `d`, ` `, `👋`]
```
### String interpolation
Basic interpolation syntax is pretty simple - use `$` before a variable name.
