--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Another example with recent trunk:
In file included from
/home/jwakely/src/gcc/gcc/libstdc++-v3/testsuite/std/text_encoding/requirements.cc:20:
/home/jwakely/gcc/14/include/c++/14.0.1/ranges: In function 'constexpr _Cont
std::ranges::to(_Rg&&, _Args&& ...)':
/home/jwakely/gcc/14/include/c++/14.0.1/ranges:9332:21: warning: typedef 'using
_RefT = std::ranges::range_reference_t<_Pattern>' locally defined but not used
[-Wunused-local-typedefs]
9332 | using _RefT = range_reference_t<_Rg>;
| ^~~~~
Where does _Pattern come from? There is no _Pattern in that function template.
The source line shows it should be range_reference_t<_Rg> instead.
_Pattern is used in lazy_split_view, split_view and join_view, none of which
are used at all by `ranges::to`. Is there some has collision going on here when
the pretty printer finds names? Does it need an additional disambiguation step
if more than one name is found?
