Of course this should be better optimized, but I use this almost 
always only to call a @system function, which get less overhead 
(or maybe even DMD is able to recognize a single call in a call, 
and optimize it away).

But I fully agree, this should be replaced by true trusted 
blocks, the sooner the better.
