Now I'm not sure what to suggest to do to fix it. I'd normally just
increase the number of stack frames that Test::Builder must look back
through by using $Test::Builder::Level, but I didn't add the extra
stack frames - Moose did. I don't know how many stack frames Moose
added and even if I were to find out, I wouldn't be able to guarantee
that this number will be the same for all future or previous versions
of Moose. It would produce some very brittle code.
Anyone got any ideas of what we should do?
I'm not very conversant on Moose, but from your description I would
think that you want to manipulate $Test::Builder::Level within the
"around" blocks for the delegated methods. You don't have any control
over the mechanism that delegates, so you can't splice in there. But you
can add such a line in the around-code. Of course, it will be brittle,
as you say, because a subtle change in Moose internals could change the
number of stack frames either in delegation or in the application of
around-code. But that is the first thing I would try, at least.
