See my comment on the exception name for the proposed change. Otherwise this looks great, thanks.

Wouldn't it be better to simply delete the name? It is truly unused, and removing the name is a more standard way to do it in C++.

Interesting. Stylistically I generally do prefer to let pointers be treated as bools directly, but in this context I'm fine with changing the code to be more generally usable by people who don't like that style and turn on warnings against it.

This fixes an Analyzer warning that shows up in Xcode 9:
https://github.com/llvm-mirror/clang/blob/master/test/Analysis/number-object-conversion.cpp
Also fixes an optional warning:
The
__unusedon the exception is needed when-Wunused-exception-parameteris enabled.Both are trivial changes that do not change functionality.
Thanks for making Djinni! We from PSPDFKit love it!
