EXPORT_FUNCTIONS is an inheritance mechanism, to let you override a
function in a class you inherit but still be able to explicitly call the
function defined by that class. Unless you have a 'myplugin' class, nothing
will translate myplugin_do_fetch to do_fetch. If you want to override a
function like do_fetch in your recipe, just override that function, don't
prefix it.
