As far as I know, william, it's not at all that subtle: anastrophe and inversion are synonymous. However, the use of 'anastrophe' is restricted to literary analysis while a whole lot of things can be inverted . Also, the use of anastrophe is an intentional literary device; don't know if you can say the same for inversion.
'Fronting' was a new one on me, though... anxiously awaiting more from Bingley.
