Class::ReturnValue is a "clever" return value object that can allow code
calling your routine to expect: a boolean value (did it fail) or a list
(what are the return values).
BTreeFolder2 is a Zope product that acts like a Zope folder but can
store many more items.
When you fill a Zope folder with too many items, both Zope and your
browser get overwhelmed. Zope has to load and store a large folder
object, and the browser has to render large HTML tables repeatedly. Zope
can store a lot of objects, but it has trouble storing a lot of objects
in a single standard folder.
nhc98 is a small, easy to install, standards-compliant
compiler for Haskell 98, the lazy functional programming
language. It is very portable, and aims to produce small
executables that run in small amounts of memory. It
produces medium-fast code, and compilation is itself quite
fast. It also comes with extensive tool support for
automatic compilation, foreign language interfacing,
heap and time profiling, tracing, and debugging. (Some of
its advanced kinds of heap profiles are not found in any
other Haskell compiler.)

The Haskell Ports Library (HPL) supports concurrent and distributed
computing in the IO monad _without_ relying on mutable variables.
Instead, it supplies monotone single-assignment variables and ports
abstractions. Ports are an abstraction for modelling variables whose
values evolve over time without the need to resort to mutable
variable, such as IORefs. More precisely, a port represents all values
that a time-dependent variable successively takes as a stream, where
each element of the stream corresponds to a state change.
Ports are ideally suited for purely functional GUI interfaces that
completely avoid the use of mutable variables. It is planned to extend
the library to interaction between different processes possibly
located on distinct processing nodes.

C->Haskell is an interface generator that simplifies the development
of Haskell bindings to C libraries. The tool processes existing C
header files that determine data layout and function signatures on the
C side, in conjunction with Haskell modules that specify Haskell-side
type signatures and marshaling details. Hooks embedded in the Haskell
code signal access to C structures and functions; they are expanded by
the interfacing tool in conjunction with information in the
corresponding C header file.
