<pre>For example:
$ cat /tmp/a.cc
namespace {
constexpr int foo = 42;
}
namespace ns {
int f() {
constexpr int foo = 42;
return foo;
}
}
$ bin/clang -c -Wshadow /tmp/a.cc
(no warning)
There's also no warning if the first 'foo' is at file-scope (i.e. without any
namespace). However, if the first 'foo' is put in 'namespace ns', then it does
warn.
Is there a reason it doesn't warn in the first two cases? It still seems like a
case of shadowing to me.</pre>
