| Subject: | Sub redefined warning when using Moose's make_immutable() |
The code below reproduces the error below and the simple patch
below seems to resolve it easily enough. The cause seems to be
that Moose's make_immutable() creates a UNIVERSAL::DEMOLISH().
Then S::D creates two of them...
Thanks,
