Re: [Groff] question regarding PIC and variable scoping

[Dwight Aplevich]

Fixing the documentation is the sensible solution.
Adding the suggested functionality is ambiguous:
Change the example to
 A: [
         box
         x = 5
       ]
    print A.x
Now, what is the value of A.x?  Better to remove "variable or"
from the documentation and add the example as proposed.
