\chapter{Introduction}

Clauses and subclauses in this document are annotated

with a so-called stable name,

presented in square brackets next to the (sub)clause heading

(such as ``[lex.token]'' for \ref{lex.token}, ``Tokens'').

Stable names aid in the discussion and evolution of this document

by serving as stable references to subclauses across editions

that are unaffected by changes of subclause numbering.

Aspects of the language syntax of \Cpp{} are distinguished typographically

by the use of \fakegrammarterm{italic, sans-serif} type

or \tcode{constant width} type to avoid ambiguities; see \ref{syntax}.
