Hi, is there a reason that when a child class is instantiated the parent
class constructor does not get called?
The obvious workaournd for this is to simply call
$this->parentConstructor(); in the child class constructor, however,
this seems strange.. 

Am i way off base here...?

Thanks
Jason

parent::__construct(), to be exact :)

Most languages i know do that ("forcing" you to call super or alike).
The only small "annoyance" i see is that parent::__construct() doesn't
automatically use the parameters that were passed to the constructor,
but i think one can live with that.
