The Size-Change Termination Principle for Constructor Based Languages, by Pierre Hyvernat:

This paper describes an automatic termination checker for a generic first-order call-by-value language in ML style. We use the fact that value are built from variants and tuples to keep some information about how arguments of recursive call evolve during evaluation. The result is a criterion for termination extending the size-change termination principle of Lee, Jones and Ben-Amram that can detect size changes inside subvalues of arguments. Moreover the corresponding algorithm is easy to implement, making it a good candidate for experimentation.

Looks like a relatively straightforward and complete description of a termination checker based on a notion of 'sized types' limited to first-order programs. LtU has covered this topic before, although this new paper doesn't seem to reference that particular Abel work.
