`Elem` proofs give existential quantification that a given element
|
||
|
|
*is* in the list, but not where in the list it is! Here we give a
|
||
|
|
predicate that presents proof that a given index of a vector,
|
||
|
|
given by a `Fin` instance, will return a certain element.
|
||
|
|
|
||
|
|
Two decidable decision procedures are presented:
|
||
|
|
|
||
|
|
1. Check that a given index points to the provided element in the
|
||
|
|
presented vector.
|
||
|
|
|
||
|
|
2. Find the element at the given index in the presented vector.
