for me, using t3lib_div::GP meant, that I'll get back a recursively 
merged array, with precedence on the POST vars. But you get either GET 
or POST vars for the same extension key. I don't see a problem in 
recursively merging GET and POST vars - and never understood why 
t3lib_div::GP is not working like that - but that's a different topic.
