I don't think this function will iterate the way you intend. You
probably won't get many helpful suggestions until you define more
precisely the nature of alist. Right now the function assumes single
item lists only and will fail with an exception if something is not
contained in the deepest list. E.g., only this type of situation is allowed:
Anything else gives an exception.
For example, this will fail with an exception:
[[1,2,3], [4,5,6], [7,8,9]]
Is that really what you want?
Hint: you need to test whether you can iterate over the elements alist.
Also, use something like "alist" and not "list" because "list" is a
