Short answer: don't do that.
Medium answer:
Mixing procedural and OO style in the same library leads to confusion
and there is little reason to support the the procedural style. Just
use the OO style.
How to actually do it:
Use Scalar::Util::blessed and and ->isa() to determine if the first
argument is an object that can be calling this method:
use Scalar::Util qw/blessed/;
sub foo {
if (blessed $_[0] and $_[0]->isa(__PACKAGE__)) {
#being called as a method
} else {
#being called procedural style
}
}
