<pre>Testcase:
class Foo {
Foo() = default;
public:
static Foo make();
};
Foo *test() {
return new Foo::make();
}
Clang emits:
<source>:8:19: error: no type named 'make' in 'Foo'
return new Foo::make();
~~~~~^
1 error generated.
Compiler returned: 1
Which was quite confusing at first. There is a 'make' in 'Foo'. Once I
confirmed that, I read the message again. Why does clang demand a type, it's
not like I said typename? What is going on. The error doesn't point at the real
bug, the extra 'new'.
In general when emitting a diagnostics with "there is no X named Y in Z" please
point out that there is a Y in Z that isn't an X. Also when possible please
point to the reason why we're expecting a type (in this case, the 'new'). In
this specific case, it would be magical if clang tried to typo-correct removing
'new' to see if the function call expression would parse and produce an
expression of the correct type.</pre>
