numbers like `15` and fractional values like `6.283185`.
* `bool`: a boolean value, either `true` or `false`. `bool` values can be used in conditional
logic.
* `list` (or `tuple`): a sequence of values, like
`["us-west-1a", "us-west-1c"]`. Elements in a list or tuple are identified by
consecutive whole numbers, starting with zero.
* `map` (or `object`): a group of values identified by named labels, like

* `map`: a group of values identified by named labels, like
`{name = "Mabel", age = 52}`.
