in reply to use deprecated;

Don't use string eval, especially when you don't need to. Try something like
sub _deprecated { my $sh = shift; require Carp; Carp::carp("$sh() is deprecated; ". "see the documentation for an alternative;"); ... } sub import { ... for (@_){ *{"$pkg\::$_"} = sub { _deprecated($_) }; }
