Tuple validation

[Rudie Dirkx]

I know a tuple isn't a PHP structure, but you can still format and validate your data like it is. For instance, I want to validate a list of tuples:

[
  [date, date, [ints], int],
  [date, date, [ints], int],
  [date, date, [ints], int],
  // etc, 20 or 100 more lines, so I don't want assoc arrays (Expect::structure())
]

The outside would be a listOf(), but a list of what? Tuples. Numeric arrays with a set amount of items that have specific types: elements 0 and 1 are dates, element 2 is a listOf(int()), element 3 is an int().

Maybe something like

$schema = Expect::listOf(Expect::tuple(
  Custom::date(),
  Custom::date(),
  Expect::listOf(Expect::int()),
  Expect::int(),
));

We can use Expect::structure() with numeric keys for that 👍
