It's also important to know that not everything in it is a variable. 
Symbols also name functions, and they're also often used as literal 
objects by themselves (e.g. when you see them quoted).  And many symbols 
that are variables are just local variables internal to functions (not 
to be confused with buffer-local variables); these shouldn't show up in 

That's why the completing-read collection that describe-variable uses 
checks whether the symbol is bound or has a variable-documentation
