Their "binary stencils" reminds me of Michael Franz' "Code Generation on the Fly: A Key to Portable Software". Franz generated the templates at runtime by caching parameterized code fragments from doing code gen on a version of the AST effective encoded in an lzw like way, so that each partial AST node would just have code generated once, so it didn't go as far as this but the stencil/template approach was there.
