Hello World Example Issues

[Jeeppler]

Hello,

I wanted to use the hello world example from this page:
https://crystal-lang.org/2013/07/10/hello-world.html

but I encountered the following error:

Can't infer the type of instance variable '@name' of Greeter

    @name = name.capitalize
    ^~~~~

I fixed the issue, by adding a property statement

class Greeter
 property name : String
  def initialize(name)
    @name = name.capitalize
  end
  ....
end

Another issue while trying to compile:

$ bin/crystal hello.cr
$ ./hello
Hello World
$

this does not work anymore. It is enough to simply use:

$ bin/crystal hello.cr

and if you want to produce an executable:

$ bin/crystal compile hello.cr
$ ./hello

My crystal version is: Crystal 0.18.2 (2016-06-17) [on Archlinux]

I think it would be a good idea to update this example.

By the way I really like that you show the hello world example as simple puts, class and block.
