Please consider the following code:
```c++
template<class T>
class confused{};
template<class T>
class test
{
void foo() {
if(this->b.confused < 1);
};
struct bar
{
int confused;
} b;
};
```
Clang rejects it by giving such considerably puzzling output:
```c++
<source>:8:32: error: expected '>'
8 | if(this->b.confused < 1);
| ^
<source>:8:29: note: to match this '<'
8 | if(this->b.confused < 1);
| ^
<source>:8:32: error: expected unqualified-id
8 | if(this->b.confused < 1);
| ^
<source>:8:33: warning: if statement has empty body [-Wempty-body]
8 | if(this->b.confused < 1);
| ^
<source>:8:33: note: put the semicolon on a separate line to silence this warning
1 warning and 2 errors generated.
Compiler returned: 1
```
We suppose that's because the compiler has found incorrect local variable name of `confused` by confusing the global template class declared above with the integer member variable declared in the nested class `bar` inside `test`
