I rate this neutrally because I am the original author of Class::Tangram, and current maintainer of Tangram.
On first inspection, this module does not appear to implement any of the features of Tangram. It implements many of the features of the Class::Tangram accessor generation package. The distinction and seperation between the two parts is one thing that Aaron appears to have missed, and a key to the great flexibility of Tangram to use whatever accessor package you like.
So Pint Is (definitely) Not (anything even resembling) Tangram.
