Isn't that simply:
my $safe_span = ...; # Whatever you need
my dt = DateTime->new(...);
croak "Bad date range" if $safe_span->contains($dt);
In fact you may want the span to be a spanset to accomodate more fine
grained controls. Is this useful enough to merit a class? I dunno.
As a minor note, it might be nice to be able to chain the Wrappers,
but I have no idea what syntax one would use.
