Unladen Swallow was an optimization branch of CPython, intended to be fully compatible and significantly faster. It aimed to achieve its goals by supplementing CPython's custom virtual machine with a just-in-time compiler built using LLVM. The project had stated a goal of a speed improvement by a factor of five over CPython; this goal was not met. The project was sponsored by Google, and the project owners, Thomas Wouters, Jeffrey Yasskin, and Collin Winter, are themselves full-time Google employees,〔(【引用サイトリンク】 People working on Unladen Swallow )〕 however the majority of the contributors to the project are not Google employees. Unladen Swallow is hosted on Google Code. Like many things regarding the Python language, "Unladen Swallow" is a Monty Python reference, specifically to the gag about the airspeed velocity of unladen swallows in Monty Python and the Holy Grail. == Achievements == Although it fell short of all published goals, Unladen Swallow did produce some code which got added to the main Python implementation, such as improvements to the cPickle module. 〔http://bugs.python.org/issue9410〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Unladen Swallow」の詳細全文を読む スポンサード リンク
