[TYPO3-dev] Bug/Feature request for t3lib_div::_GP (and alike)

That's the point - I don't get it from GET if there is also a parameter 
with the same namespace in POST.

My use case:

I'm using your extension skpagecomments and attached it via TS on every 
page in a toolbar at the bottom of the website, only displaying the 
button 'show comments (n)' by default. When you click the button and 
submit the piVar tx_skpagecomments_pi1[showComments] with GET, I want to 
hide/remove the button from the bottom toolbar and show the comments 
with a comment form right above the toolbar. Therefore I use a 
condition, checking for this piVar and set/unset TS-objects accordingly. 
I use this condition:
[globalVar = GP:tx_skpagecomments_pi1|showComments = 1]

This is working fine, unless I try to add a comment. When submitting the 
comment form, the condition will fail and the comments get shown inside 
the toolbar instead above.

And this is because t3lib_div::_GP is not returning a merged array to 
the matchcondition class.

Ok, now I know that I can check directly for a GET var, but I'd like to 
stay a bit more flexible so that I don't need to care if the parameter 
is coming from GET or POST.
