* `string`: a string. Can be defined between double quotes `"string"`. Support [text interpolation](#text-interpolation). Support [escape codes](#escape-codes).
* `pair`: a couple of values. Types can be mixed. Can be defined using colon `"key":5`. Pairs named by a string that is also a valid identifier can be created using the `key=5` shorthand syntax.
* `pair`: a couple of values. Types can be mixed. Can be defined using equal sign `"key"=5`. Pairs named by a string that is also a valid identifier can be created using the `key=5` shorthand syntax; `key` will not be interpreted as the variable `key` but the string `"key"` (if `key` is a variable and you want to force the use of its value as a key instead of the string `"key"`, you can wrap it in parentheses).
* `type`: a couple of values. Types can be mixed. Can be defined using colon `expr::type`. The second value is used in type checks, this is intended to be use to give a custom type to a value.

* `string` -> `string`
* `list` -> `table`. Pair elements in the list will be assigned as a key-value pair in the Lua list and its index skipped in the sequential part, e.g. `[1,2,"key":"value",3]` -> `{1,2,3,key="value"}`.
* `list` -> `table`. Pair elements in the list will be assigned as a key-value pair in the Lua list and its index skipped in the sequential part, e.g. `[1,2,"key"="value",3]` -> `{1,2,3,key="value"}`.

`a;`: evaluate a, discard its result, returns nil.
`a : b`: evaluate a and b, returns a new pair with a as key and b as value.
`a = b`: evaluate a and b, returns a new pair with a as key and b as value. If a is an identifier, will interpret it as a string (and not a variable; you can wrap a in parentheses if you want to use the value associated with variable a instead).
`a :: b`: evaluate a and b, returns a new typed value with a as value and b as type.
