Well, "safety" is a lot of things so you have to be a bit more specific than that about your use-cases. And I can't really answer it either way - I think WvO has to chime in about that himself - but I can point to some things that might give you some idea of what to expect. Here's what WvO wrote a few weeks ago when he shared Goose on twitter:
> Goose: my latest programming language. Safer, faster and less memory than Rust/C++ for algorithms where tightly packed, flat data structures matter.
> It can represent more kinds of data structures as flat, pointer-free bytes than any language I know.

So one way to answer might be: how often do you reach for unsafe when using Rust? If you don't I guess Rust is safer. If you do… it gets trickier.
As for UB, I guess you could try looking through the spec and/or the reference? Like, the code is mostly generated by Claude after WvO wrote a specification. If it were anyone else I'd be worried, but given WvO's cv I actually suspect that means the spec leaves basically no ambiguity.
However, Goose compiles to C. Does that by definition mean UB sneaks in, or is there a "UB free" C subset? I don't write C, so I don't really know.
