• Passing hashref to constructor (Score:1)

  Hi, regarding

  Further, Object::Tiny lets you pass your params in directly, without having to wrap them in an additional HASH reference that will just be copied ANYWAY inside the constructor.

  and

  Object::Tiny accessors are identical in speed to Class::Accessor::Fast accessors, but Object::Tiny constructors are TWICE as fast as Class::Accessor::Fast constructors, DESPITE C:A:Fast forcing you to pass by reference (which is typically done for speed reasons).

  Speed is not the only reason, and I believe its no

    ..the error message from perl will tell me the exact
          line number where I made the mistake, and not the line inside your
          constructor where you assign @_ to an hash (the common approach).
    
    That's what Perl Best Practices recommends too, I think,
    although it looks terrible.

      Yes it is... As for the syntax, it grows on you.
      
      But truth be told, there is no need to use that trick to get the proper error line. If module authors that accept hashes add this line:
      
          croak('FATAL: odd number of parameters, ') if @_ % 2;
      
      (Use Carp qw( croak ) at the top also)
      
      It would also work.
      
      Best regards,
