To be clear, a new direction wasn't decided at the meeting. The item being
revisited is how tightly coupled metaprogramming and the existing
constexpr/consteval mechanisms will be. The constraints introduced by such
a tight coupling make reasoning difficult in a lot of cases. The circle
programming language <https://www.circle-lang.org/> (a C++ derivative) went
with a different set of tradeoffs for metaprogramming and ended up with
something arguably more compelling and simple from a user standpoint. It is
also a lot faster at compile time.

We plan on doing a thorough investigation into this so we can clearly
articulate what the tradeoffs are and what, if any, tweaks (hopefully) or
fundamental changes (hopefully not) would be interesting to make with the
current design before the next meeting.
