This should be enough to indicate order of arguments, types, and so on.
**Patterns often, but do not always, indicate types.** Typed patterns are written as `foo as :bar`,
where the type is indicated by the keyword. Possible ludus types are: `:nil`, `:boolean`, `:number`, `:keyword` (i.e., atomic values);
`:string` (strings are their own beast)'' `:tuple` and `:list` (indexed collections); `:set` (again, their own beast),
where the type is indicated by the keyword.
Possible ludus types are: `:nil`, `:boolean`, `:number`, `:keyword` (atomic values);
`:string` (strings are their own beast); `:tuple` and `:list` (indexed collections); `:set` (sets are specific),
`:dict` and `:ns` (associative collections); and `:ref` (references).
**Conventional types.** Ludus has two types based on conventions.
* _Result tuples._ Results are a way of modeling the result of a calculation that might fail.
The two possible values are `(:ok, value)` and `(:err, msg)`.
`msg` is usually a string describing what went wrong.
To work with result tuples, see [`unwrap!`](#unwrap) and [`unwrap_or`](#unwrap_or).
That said, usually you work with these using pattern matching.
* _Vectors._ Vectors are 2-element tuples of x and y coordinates.
The origin is `(0, 0)`.
`add` and `mult` can take vectors as well as numbers.
