The description of take-right and drop-right reads
For a legal i, take-right and drop-right partition the list in a
manner which can be inverted with append:
(append (take flist i) (drop flist i)) = flist
This example is a duplicate of take and drop .In addition, both examples
are incorrect because append requires proper lists, while flist can be
proper or dotted.
The take example should be modified to read:
> For a legal i and proper list x, take and drop partition x in a
manner which can be inverted with append:
>
> (append (take x i) (drop x i)) = x
And the take-right example should be modified to read:
> For a legal i and proper list x, take-right and drop-right partition
x in a manner which can be inverted with append:
>
> (append (drop-right x i) (take-right x i)) = list
