Trusted blocks are used for safety inference in generic code, so 
that only code outside trusted blocks affects inferred safety of 
the generic function. Normally you should be fine by marking the 
trusted function with one @trusted attribute and be done with it, 
that's what it was designed for.

And it also made code cleaner than with unsafe blocks sprinkled 
everywhere.
