[TYPO3-mvc] TypoScript manipulation per object property

I don't think so, because FLUID itself is using 
Tx_Extbase_Reflection_ObjectAccess to resolve the values. Also using 
hooks wouldn't be compatible with v5 AFAIK.

yes - don't do it in the getters - it's clearly part of the view and not 
the model.

yep - I think using something like the "alias" viewHelper might help 
here - so a viewHelper where you pass a array/object to and it will be 
processed and reassigned to the view again. Your viewHelper could then 
do two things:
a) preprocess all values and assign them as array back to the view 
(easiest, yet worst solution as you produce much overhead with 
preprocessing unused properties)
b) use proxy classes which will fetch and process the return values on 
demand (the way I'd go)
