[ANNOUNCE] functional 0.7.0 released
Collin Winter
I have released version 0.7.0 of my functional module, a collection of
higher-order and functional programming tools for Python. Currently
offered are tools for function composition, partial function
application, plus filter, flip, foldl, foldr, map, scanl and scanr
functions.
Two version of the release are available: one is written in pure
Python and aims for maximum readability and portability. The other is
coded as a C extension module and is focused on raw performance.
Where to get it:
#########
functional is available from the Python Package Index at
http://cheeseshop.python.org/pypi/functional/
Both source tarballs and Python Eggs are available for both the pure
Python and C releases. Eggs are available for Python versions 2.3, 2.4 and 2.5.
Release Notes
########
+ functional now includes map() and filter() functions. These are
roughly equivalent to the Python built-in functions, though without
some of the weird/incorrect behaviour of the built-ins.
Specifically:
functional.map() works like the built-in, except functional.map() 1)
always takes a single iterable, and 2) doesn't support the None
nonsense that the built-in does.
functional.filter() works like the built-in, except
functional.filter() 1) iterates over subclasses of str, unicode and
tuple correctly, 2) doesn't support the None nonsense that the
built-in does, 3) always returns a list, unlike the built-in.
+ Several reference counting-related bugs have been squashed in the C
implementation.
+ The test suite has been enhanced to do reference count checking
after each test, making it much easier to track down future errors in
the C implementation.
+ The C implementation now supports Python 2.3, in addition to 2.4 and 2.5
As always, feedback welcome!
