Ah right, thank you! I went through evil-maps.el but overlooked it.  Sorry.

The thing is now that when I bind TAB to my expand function and hit
TAB in replace state it doesn't overwrite the existing text with the
expansion but inserts the expansion.  I think I would fix that by
binding TAB in replace state to a wrapper of my expand-function that
first determines the expansion, inserts it, and then deletes a string
that is as long as the expansion following the expansion.  While this
should work, I'm wondering: is there a better way to do this?
Specifically, I'm wondering if evil has a way to make the overwriting
transparent for the expansion function.

Best,
