(synopsis "Abstract, parameterized interface to mutable Deques for Haskell")
(description "This Haskell package provides an abstract interface to
highly-parameterizable queues/deques.
Background: There exists a feature space for queues that extends between:
@itemize
@item Simple, single-ended, non-concurrent, bounded queues
@item Double-ended, threadsafe, growable queues with important points
inbetween (such as the queues used for work-stealing).
@end itemize
This package includes an interface for Deques that allows the programmer
to use a single API for all of the above, while using the type-system to
select an efficient implementation given the requirements (using type families).
This package also includes a simple reference implementation based on
@code{IORef} and @code{Data.Sequence}.")
