<P>[Accepted at the November, 2020 meeting as part of paper P1787R6 and
moved to DR at the February, 2021 meeting.]</P>

<P>According to 7.5.6 [<A href="https://wg21.link/expr.prim.lambda#7">expr.prim.lambda</A>] paragraph 7, names
appearing in the <I>compound-statement</I> of a
<I>lambda-expression</I> are looked up in the context of the
<I>lambda-expression</I>, ignoring the fact that the
<I>compound-statement</I> will be transformed into the body of
the closure type's function operator.  This leaves unspecified
how the <I>lambda-expression</I>'s parameters are found by
name lookup.  Presumably the parameters hide the corresponding
names from the surrounding scope, but this needs to be specified.</P>
