Synopsis

Grouping with the key

Arguments

:: Eq b
=> (a -> b)	The given mapping function.
-> [a]	The list of items to group into non-empty sequences.
-> [(b, NonEmpty a)]	The list of groups.

Group the given list of items to a list of NonEmpty 2-tuples with the "key" and the value for a given mapping function.

Arguments

:: (b -> b -> Bool)	The given equivalence relation.
-> (a -> b)	The given mapping function.
-> [a]	The list of items to group into non-empty sequences.
-> [(b, NonEmpty a)]	The list of groups.

Group the given list of items to a list of NonEmpty 2-tuples with the "key" and the value for a given mapping function and equavalence relation.
