Programming with only exceptions!
summary
Builds a toy language called Hurl that uses only exceptions for control flow and claims it can express any computation; implements two forms of exceptions — a destructive hurl and a nonunwinding toss — plus three main features (variables, anonymous functions, exceptions). Shows mechanical translation of Python examples like factorial, ships a standard library and custom licenses, runs as a tree-walk interpreter with OS-limited call stack, and admits toss is buggy and debugging is painful.
