 Replace isValid() calls with assert() 
There's more value on showing how `assert()` displays the validation
messages than simply showing if `isValid()` returns `true` or `false`.

However, that increases the chances of having outdated documentation, so
I created a doc linter that updates the Markdown files with the
correct message.

Subset

  • Subset(mixed[] $superset)

Validates whether the input is a subset of a given value.

v::subset([1, 2, 3])->assert([1, 2]);
// Validation passes successfully

v::subset([1, 2])->assert([1, 2, 3]);
// → `[1, 2, 3]` must be subset of `[1, 2]`
