Hi Kenton / to whom it may concern!
I’m using capnproto and when I try to use the library I seem to be getting the
following errors from schema.capnp.h. They seem related to the “Which” enum
with -Wshadow -Werror.

../../../../../../ext/capnproto/c++/src/capnp/dynamic.h:35:

I think this is because these “Which” enums are declared as “enum” and not
“enum class.” I think this may be unavoidable as long as I’m on the 0.8 release
version (unless I want to make local edits, which frankly I’m not excited to
do), so I may have to do -Wno-error=shadow. However, I was wondering if in
future versions it would be possible to fix this so that
Type::AnyPointer::Unconstrained::Which can be of type “enum class” instead of
just a pure “enum.” Would there be any problem with this? Am I misunderstanding
something? It seems like the project uses C++11/14 in a number of places
already, so this is probably not the biggest deal?
Cheers,
