The infinite loop is inside Devel::Declare::Context::Simple->strip_attrs. That should be fairly simple to make a test for and report upstream.

Wait a second, it still effects our users. It's still our bug even if we didn't report it.

Did it get reported upstream? If so, what's the ticket # so we can link it to this one.

When it gets fixed upstream, will need to remember to bump our version requirement.

Meanwhile, can we work around it?
