Exceptions all Over the Shop: Modular, Customizable, Language-independent Exceptio...
summary
Claims a language-independent Java exception layer library that untangles exception handling into 10 modular components, uses five generic type parameters, and runs atop the JVM without assuming host-language internals. Demonstrates refactoring a Neverlang JavaScript: replace a custom memory with the layer by adding 369 LOC and removing 71 LOC, then add conventional try/catch/finally and retry and resume handlers (unconventional) with no further core changes. Also implements a LogLang backup-with-prompt handler in 77 lines, proving the approach works.
