The fact that there is a bad example doesn't mean it can't be done right. Take a look at Eiffel for an example of simple, readable type declarations.

    ... looks to me like the types are written after the typed variables/parameters. Hence ... looks like it's not using prefix types. All I'm trying to say is that we should look at C and NOT repeat it's seemingly bright ideat to put the type before the variable ending up putting the type information all around the variable.

      In Perl 6 you can put the type either before or after, taking end-weight into account. So 
          my Int @array;

      [download]
      is equivalent to 
          my @array of Int;

      [download]
      which in turn is really short for 
          my @array is Array of Int;

      [download]
      so it's easy to see how you can end up with cool things like 
          my @array of Hash of Tree of Int;
