Dear Diego,

Thanks for caring to reply.

In fact, it is not a business requirement or something like that. 
  My question is purely on academic interest.
The if_condition being costly is not exaclty what I want to 
escape from.  I am thinking why I am forced to execute the 
condition, when I know that I will not be benefited.

Thanks,
