[TYPO3-core] RFC #17420: Add LOOP cObject

That's what I just wanted to clarify.

Fine for me as long as there is a clearly visible difference between

myElement = LOOP
myElement.input = whatever

and

myElement = TEXT
myElement.data = whatever

So +1 for this one.

Still I think "input" should get stdWrap properties, even though we 
can't return arrays with stdWrap yet. But anything like

myElement.input.if.isTrue.data = whatever

would still be helpful. And we can easily add array related functions to 
stdWrap later on, without having to touch the LOOP element again.

Just my 2 cents
