"Any::Moose" picks Mouse if it is available, then falls back to Moose.
Unless the end user requests Moose. From the docs:
"By default, Mouse will be provided to libraries, unless Moose is
already loaded -or- explicitly requested by the end-user. The end-user
can force the decision of which backend to use by setting the
environment variable ANY_MOOSE to be Moose or Mouse.
Note that the decision of which backend to use is made only once, so
that if Any-Moose picks Mouse, then a third-party library loads Moose,
anything else that uses Any-Moose will continue to pick Mouse.
So, if you have to use Mouse, please be considerate to the Moose
fanboys (like myself!) and use Any-Moose instead. :)"
