hello, Oscar - why don't you try it?
notice how 'Class' is a keyword so you can't name a class 'Class'
notice how if you use '$SESSION' it won't work even if you start
the session correctly... $_SESSION on the other hand will work better :-)

this is true.

that wouldn't work - at least none of the methods would be available for use -
in affect you have an incomplete object from which you can retrieve all the
properties but not call any methods.

personally I have a Session handler class with which I can
register classes to be automatically _if_ the session is started.... ;-\

...mostly because I use lots of classes - and loading them all, everytime is
not a good idea - unless you like consistently slow pages :-)
