error: Could not compile `flamer`.

Here's a simple patch to workaround the compile failure by ignoring foreign items, statements, and expressions. (But it would be really nice if these could be annotated by flamer!)

Thank you for giving me notice!

Statements and expressions have no name, so I wouldn't know how to flame them. Perhaps I'll figure something out later.
