I don't agree with this, sometimes you actually save a lot of assigning things 
and adding variables that are only used to bypass something that should not 
happen because you already determined your return value. So I think it can 
add unncessarily to the complexity of the code.

I don't think it's a refactoring principle, but more style of coding. What is 
important though imho is to keep a stirct signature for the function, ie. 
only one return value type.

I didn't look into the code but remember that strcmp and === are not 
equivavalent strcmp is binary safe, but does not check the type of the 
parameters, but does on-the-fly casting.


(strcmp('2',2)===0)  => true

'2'===2 => false
