Well, there's nothing in the actual docs to say that this functionality
is present, so it's not really a bug that it doesn't work.
A simple global verbosity variable is no good anyway. You want to be
able to temporarily switch all objects warn behaviour, but then be able
to switch it back to whatever their verbosities were to begin with. If
you just set Bio::Root::VERBOSITY to something, how would any method
(ie. &warn) know if you wanted that verbosity to be used now all the
time, or if the verbosity set on the root instance should be used? I
suppose the default of it could be undef, and you set it back to undef
when you don't want a global verbosity, but is that very nice?
