Drawbacks of Moose

Why you shouldn't use Moose?

• Moose has a fairly heavy compile-time cost.
• Not appropriate for non-persistent environments (vanilla-CGI, etc.)
• We are looking into using .pmc files to reduce this burden.
• Some Moose features can be slow at times.
• However speed is directly proportional to the amount of features used.
• Nothing is life is free.
• Extending non-Hash based classes is tricky.
• The most common example is the IO::* family of class.
• I recommend Class::InsideOut or Object::InsideOut for this (or delegation, however ...).
• Some delegation features do not play well with AUTOLOAD
• AUTOLOAD is evil anyway :)
