pure and custom new / delete

[Benjamin Thaut]

As delete and new / delete overloading is deprecated and it was 
recommeneded to write tempaltes to repalce these expressions I did so.

But now as everything starts to work out pretty nice I've walked into 
the 'purity' issue. Pure functions are only allowed to call other pure 
functions and as far as I know there is no way to make functions 
"trusted pure". But I would need to make certain functions "trused 
pure", espeically my new and delete replacements. Any suggestions how to 
do this?

Kind Regards
