Aha, I dumped a big AST to JSON, searched for a `CXXBindTemporaryExpr` inside a
`VarDecl` and came up with this example:
```
/Users/doug/Desktop/makestring.cpp:10:7: warning: function with 'nonblocking'

[-Wfunction-effects]
10 | auto str = String::make();

It may be a little annoying to get two warnings but technically I think there
really are two implicit calls to the destructor. (right? the result of
`String::make()` might be getting moved-from but there's still an implicit
destructor.)
