How to lazy evaluate for the first return value of FilterMap

[kcmvp]

FilterMap function return a value and a bool value to identify skip current value or not. If the return bool value is false then no need to return the value( just zero or nil) enough, is there a way to defer the object creation? My case is use FilterMap to process a huge collection

@kcmvp, even if the value is returned it will not be used anywhere. So there the object creation is being done in the callback function. If you want the the return of bool when false should be zero or nil , you can write that implementation in the callback function itself.
