Runtime syntax this instruction set cannot express faithfully, or that carries no runtime semantics. Every variant names one rejected construct; there is no catch-all. None of these occur in the executable corpus.

Variants

WithStatement

with opens a dynamic scope the register model cannot represent.

UsingDeclaration

using/await using explicit resource management (no disposal opcode).

LabeledStatement

A labeled statement (no labeled control-flow target model).

LabeledJump

A labeled break/continue.

DebuggerStatement

debugger is a host breakpoint request with no bytecode.

EnumDeclaration

A runtime enum (const enums are type-only and already erased).

NamespaceDeclaration

A runtime namespace/module block.

RuntimeImportEquals

A runtime import x = require(...) / import x = ns declaration.

RuntimeExportAll

A runtime export * from ... (no dynamic per-name re-export).

ExportAssignment

An export = assignment.

DecoratedDeclaration

A decorated declaration.

DynamicImportExpression

A dynamic import(expr) whose specifier is not a string literal.

ImportDeclarationInScript

An import declaration is invalid in a classic script.

ExportDeclarationInScript

An export declaration is invalid in a classic script.

DynamicImportInScript

A dynamic import expression is invalid in a classic script.

ImportMeta

import.meta (no host meta-object primitive).

EscapedIdentifier

An identifier spelled with unicode escape sequences.

NonDecimalBigInt

A non-decimal (0x/0o/0b) bigint literal.

ReturnOutsideFunction

A return at module top level.

DerivedConstructorShape

A derived constructor that is not an implicit constructor or a single direct top-level super(...) call.

ThisBeforeDerivedSuper

A derived constructor references this before its direct super(...).
