In XTZGZoReX's defence, his suggestion isn't actually based on something PHP already does.
What he wants is to be able to create an alias named /foo and be able to call it with /foobar, in much the same way as /timer can be called with /timername.
This idea would likely be quite difficult to implement and slow once implemented. I can't think of any situation where having it would be a significant advantage.
