I will tell you what I prefer, put it all into the result.  My reason: 
I hate the idea that a custom library, or even the Rev IDE, will not 
allow my script to continue because it ran into an error doing something.

For Example:  When someone tries to modify an image with JPEGCompress, 
sometimes the IDE hick ups and spits out the "can't open file (or mask 
file)" error and stops my script completely.  This is extremely annoying 
when it could just return that same error in a result which my script 
could test for and decide what to do.

It's just easier on the target and gives the programmer more control.
