Whether Python used to raise OverflowError in case of underflow was platform- dependent (it did when the platform mat...

Python is a dynamically typed language, like Smalltalk or Scheme, that relies on extensive runtime checking to ensure the correct use of built-in operations. Soft typing [Cartwright] is a mechanism to statically check programs in dynamically typed languages to detect errors and eliminate unnecessary runtime checks; the analysis is integrated with the programming environment ...
