I think I understand you mean here.
In ATS3, I plan to have an evaluator for evaluating
compile-time constant expressions. This evaluator
can evaluate an expression like tlist_append(constant1, constant2).
Of course tlist_append needs to be defined at the sort level first.

My one example, serialization of nested records from a tlist of
@(string,t0ype), turned out to not need append. Anyhow, that's blocked for
now, since I don't think you can reflect a template-argument string literal
to the value level.
But more generally, a convenient way to write functions betw

Could you show an example of intended use of tlist_append?

Is it possible to write (proof) functions from datasorts to datasorts? For
example, if we have
datasort tlist =
| tnil
| tcons(t0ype, tlist)
it would be nice to write something equivalent to
tlist_append : (tlist, tlist) -> tlist
tlist_filter: (tlist, (tlist) -> bool) -> tlist
t
