I've been reading a lot of discussions about loading expression from external files and most of them suggest on creating variable in the load script using peek. Here are my thoughts
Downside of creating variables in the Script:

- For any additions or removal of any expression you will be forced to edit both your external file and the load script.
- Extra line of scripting for each variable
