I like the idea that of restricting what is passed into function;

void logIfFalse(bool condition, lazy pure nothrow @safe string message);

In wich case, expression passed needs to be checked for these restrictions.

But I would leave the semantics of current lazy as is, or with one adjustment: 
It would be better if the compiler could make sure it is executed only zero 
or one time (but I don't think it has much practical advantage).
