For example, in Python you could add behaviour to object initialisation by creating a custom __init__ method in a metaclass.

I'm curious - how do you see Perl or C++ or Java lacking this behavior? I know that my personal baseclass has the following lines in the new() call:
That way, I can define a method init() in every class that derives from this baseclass (which is just a way of encapsulating getter/setter/mutator generation and enforcing attribute creation) and I seem to have the same behavior you're touting Python for ...?
my $init = $self->can('init');
$init && $init->($self, @_);

The idea is a little like C++ templates, except not quite so brain-meltingly complicated. -- TheDamian, Exegesis 6
