<P>[Resolved by <A HREF="2631.html">issue 2631</A>, which was accepted as a DR at the November, 2022 meeting.]</P>



<P>Non-static data member initializers get the same late parsing
as member functions and default arguments, but are they also
instantiated as needed like them?  And when is their validity
checked?</P>

<P><B>Notes from the October, 2012 meeting:</B></P>

<P>CWG agreed that non-static data member initializers should be handled
like default arguments.</P>

<P><B>Additional note (March, 2013):</B></P>

<P>Determining whether a defaulted constructor is <TT>constexpr</TT> or
not requires parsing the class's non-static data member initializers;
see also <A HREF="1360.html">issue 1360</A>.</P>
