Your code example is nearly correct  
[https://crystal-lang.org/api/1.10.1/NamedTuple.html#each(%26)%3ANil-instance-method](https://crystal-lang.org/api/1.10.1/NamedTuple.html#each%28%26%29%3ANil-instance-method)

```crystal
some_var : NamedTuple(name: String, age: String) = {name: "crysal", age: "very long"}

some_var.each() do |key, value| 
  puts key.to_s
  puts value
end

```

The syntax breakdown is:  
variable\_name : TheTypeYourAreSpecifying = `its_default_value`

So in your example you named your `NamedTuple` as `array`, which I think is causing some confusion.
