Yes, it should. We'll update the PR to support that. Thank you for noticing and mentioning this.

Likewise in the future we'll probably want to add support for `restrict`. It's not necessary for this PR since `throw/throws/exception` is only useful in C++ but when parsing Doxygen comments in C codebases we'll want to have the option of supporting that.
