Free function doesn't suit better than actual method. The issue 
is absence of the actual method.

opUnary method has priority over alias this, which does make 
sense because alias this is chosen only when it is impossible to 
apply operation over A type. If this request is approved and 
compiler has opUnary definition outside type (which suits better 
then alias this) such function would hijack alias this. If not, 
there is a new case when something is going special than at usual 
cases and only for the purpose of writing operator overloading 
methods outside the body of the type.
