Thanks. I thought long about whether to handle the fundamental types
differently than user-defined types and decided against it. The
capture-everything-by-reference-by-default model is easy to explain and
reason about. Special cases can be handled on a per-domain basis as needed.

By-value capture of fundamental type is the classical way people do it in hand-made ET code. The ad-hoc support in proto is IMHO better as you may really want to capture reference and by the status of Proto of a EDSL toolkit, flexibility is really wanted :).
