So I just started learning Crystal because I like both Ruby and C, but I just can't get the hang of the syntax yet. I think I am close, but I'm stuck with this error.  

`no overload matches 'Array(Person)#+' with type Person 
Overloads are:
- Array(T)#+(other : Array(U))
people += Person.new("Person#{id}")`

Here is the code.

```
class Person
    def initialize(name : String)
        @name = name
        @age = 0
    end

    def name
        @name
    end

    def age
        @age
    end
end

people = [] of Person
counter = 0
id = 0

loop do
    id+=1
    people += Person.new("Person#{id}")

    counter+=1
    break if counter = 5
end

puts(people)

```

What am I doing wrong?
Thanks in advance!
