If a few implementations decide to use the working directory as base for 
"include" file names - which wouldn't be such far-fetched decision, 
given that "load" works the that way on most systems - one couldn't rely 
on, e.g., the including file's directory to be searched. Which would be 
bad. (However, I might overestimate the likeliness of this happening.)
