Is the key not a member of the map?

notMember 1 (fromList [(5,'a'), (3,'b')]) == True

Is the element not in the set?

An empty list that can be used to indicate that there are no type arguments allowed in cases where HsConDetails is applied to Void.

notElem is the negation of elem.

Examples

Basic usage:

>>> 3 `notElem` []
True

>>> 3 `notElem` [1,2]
True

>>> 3 `notElem` [1,2,3,4,5]
False

For infinite structures, notElem terminates if the value exists at a finite distance from the left side of the structure:

>>> 3 `notElem` [1..]
False

>>> 3 `notElem` ([4..] ++ [3])
