PHP refactoring: function aliases? Need opinions.

Wondering if there's a way to avoid the duplication of a couple of helper functions I did for my tests:

function birth($action, $arguments)
{
    ...
}

function raw()
{
    return birth(__FUNCTION__, func_get_args());
}

function make()
{
    return birth(__FUNCTION__, func_get_args());
}

function create()
{
    return birth(__FUNCTION__, func_get_args());
}

birth is where everything happens obviously. I'm pretty sure I don't know PHP enough and there's a better way rather than copypasting each function. It doesn't really matter per se, but I'm curious. Any thoughts?
