NAME

B::XSUB::Dumber - B::OPCheck demo for microoptimizing XSUB invocation.

SYNOPSIS

        use Scalar::Util qw(blessed reftype);

        {
                use B::XSUB::Dumber qw(blessed reftype);
                reftype($thingy);
        }

DESCRIPTION

Certain XSUBs don't need lots of fluff from pp_entersub to be invoked since they don't do anything fancy. For XSUBs fitting this description this module lexically replaces the implementation of the entersub ops calling them with a much simpler version that doesn't do anything except invoke the XSUB function pointer from the CV.

This is meant mostly as a demo of the sort of thing B::OPCheck lets you do, so please don't take it too seriously or rely on it in any way.
