Summary
Functions
Appends quoted
to the list unless it is already present, determined by equality_pred
.
Appends quoted
to the list
Finds the index of the first list item that satisfies pred
Returns true if the zipper
is at a list literal
Moves to the list item matching the given predicate
Prepends quoted
to the list unless it is already present, determined by equality_pred
.
Prepends quoted
to the list
Removes the item at the given index, returning :error
if nothing is at that index
