First step at adding exceptions (#12789) Summary: This is a first step towards adding exceptions. We need minimal support in order to begin converting the torch library to weak script mode (which is the main goal here). Some limitations (that are documented in the tests & compiler): 1. Cannot assign exceptions to variables 2. Any name after raise is being treated as a valid Exception 3. No control flow analysis yet. Below a will be undefined: if True: a = 1 else: raise Exception("Hi") return a Pull Request resolved: https://github.com/pytorch/pytorch/pull/12789 Differential Revision: D12848936 Pulled By: eellison fbshipit-source-id: 1f60ceef2381040486123ec797e97d65b074862d 2018-10-30 20:20:26 -07:00			`(def`
