Seed7 as inspiration for Ada202X

As seen in Seed7's FAQ and reference webpages, Seed7 has a variant of some of the bold fresh features that were mentioned by various posters in the recent Ada202X-wishlist thread here on comp.lang.ada.  For example, Seed7 has:
1) types as truly first-class citizens (as objects with stage-n+1 reflection of properties of types generated in stage-n) that can blossom in the next stage of:
2) multistage programming that not only rejects modern C++'s misguided poor-man's emulation of functional programming, but also fundamentally integrates/imbues the concept of a generic/template throughout the rest of the language, which blurs the line between:
3) stage-n interpreter within the stage-n+1 compiler as a compile-time source-code-generator-like presentation of source code to the n+1 stage that not only rejects C's, C++'s, and gnatprep's misguided preprocessor, but Seed7's breadth of compile-time variant selection/generation seems to go so far as to eclipse such Ada's narrower-vision patchwork of discriminants and child-package substitution for tailoring source-code to compile in multiple variant targets or for multiple variant problemspaces.
4) extensible syntax for creating domain-specific problem-space-specific "little languages" (à la OCaml & its p4), as well as a multistage progression of compiler-frontends because:
5) all statements are effectively user-defined syntax (with some basic usual branching constructs provided as a sort of standard library);
6) multiple dispatch.

The worst complaint that I have with Seed7 is that it is not a proper superset of Ada, especially regarding the lack of low-level bit & bit-string declarations and the apparent lack of ability to declare constraints on subtypes.
