Norm 0.11

Norm 0.11 completes the vertical implementation of nominal exceptions and structured exception control flow.

Language

std.core.Exception is the class root of every throwable exception.
throw accepts non-nullable, non-generic Exception subtypes.
try supports ordered catch clauses and an optional finally clause.
Catch selection uses the dynamic type, with specific types preceding general types.
Finally covers normal, return, throw, break, and continue completions and may replace the prior completion.
Toolchain runtime failures retain separate error codes and are not intercepted by user catches.

Syntax, Semantic, Bound, and Core use dedicated exception-control nodes and catch-local bindings.
Core identity advances to Schema V7 and Language Semantics V7.
Truffle preserves exception object identity, nominal inheritance matching, source locations, and guest stacks.
The parser, formatter, Language Server, VS Code grammar, and cross-package compiler share the same exception model.
