Demonstration source file

When using a boxed expression on a BOOL literal (i.e. @(YES) or @(NO) ), an
integer-type NSNumber is returned instead of a boolean-type NSNumber.

I'm not sure if it's a bug on the 'true' and 'false' boxed booleans, but it
should definitely behave as a boolean for YES and NO.

You can see this behaviour by converting it to JSON. The attached demo file can
be compiled with, assuming a default Xcode installation:

xcrun clang main.m -framework Foundation -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/
&& ./a.out
