<P>[Accepted as a DR at the June, 2024 meeting.]</P>



<P>The following fragment,</P>

<PRE>
  int f() {};
</PRE>

<P>is syntactically ambiguous.  It could be either a
<I>function-definition</I> followed by an <I>empty-declaration</I>,
or it could be a <I>simple-declaration</I> whose
<I>init-declarator</I> has the <I>brace-or-equal-initializer</I>
<TT>{}</TT>.  The same is true of a variable declaration</P>

<PRE>
  int a {};
</PRE>

<P>since <I>function-definition</I> simply uses the
term <I>declarator</I> in its production.</P>

<P><B>Additional notes (May, 2024)</B></P>

<P>
<A HREF="2876.html">Issue 2876</A> introduced a framework to
distinguish the parsing.  Its resolution was extended to also resolve
this issue.</P>
