Re: optional int parameters for a proc

[Arrrrrrrrr]

But that's not how overloading in this case would work, as proposed by evacchi. 
If the function performs a different action depending on whether the value is 
nil or not, it might require totally different function to handle that case. 
Otherwise, putting the logic to adquire this value in a different function 
saves you an import and bloated code. I'd rather write a second function than 
import options, some(5) everytime.
