DRY/Functional Programming?

I am working with the v1 runtime. Is there an elegant way to avoid rewriting the same code over and over for different timing scripts? E.g., lets say I want to include the same hotkey mapping in all of my tasks; is there a way to avoid repeating myself rather than having to explicitly include this code in every task's timing file?

Or what if I want to add functionality, i.e., wrap, to a runtime function?

I made a new function for it. Download the NIMH ML package again. Then you will be able to use include().

You can define the wrapper in the timing script.
