I always thought of Iron as the foundation for Rust. But then again, I'm told I like dad-jokes.

This would unfortunately be confusing since iron is already a rust web framework.

But the language is named after tree mould, not oxidized metal. :Shrug:

This is still a open question! We made no decision on the name yet.

Personally I think anything beyond "Rust Foundation" or "Rust Language Foundation" risks merely confusion over purpose.

I agree. Something like Rust Language Foundation has both the clarity and gravity that it deserves. We will always have crates and components for fun names.

The "Ferrous Foundation" is appealingly alliterative. But it also makes it easier to expand the focus beyond Rust — which is probably a negative, because it makes it harder to concentrate on core competency.

Every foundation is engaged in a perpetual struggle over whether to expand its mission. But in the vast majority of cases, mission creep weakens the organization's ability to achieve its primary goals.

(Crafting a concise mission statement will help inoculate against mission creep, and should be done regardless.)

The Fe foundation, or "FeFo" in short.

Could call it Oxygen, or Oxidize, or something along those lines

Oxidize is taken by a Rust conference :). oxidizeconf.com

"Iron" seems like a fun/nice option.

"All your references belong to us"...

Can be the motto..

The Krusty Krab?
