#3This seems..absurd for a programming language with goals like Rust. Why isn't this a compiler option? Just set -nopanics and the compiler errors and flags anything which is pulling in a panic at the very least?

Yeah, I'm fairly sure that there is such a flag/toplevel attribute... and if there isn't, there should be one.
It also feels like most of the pains on avoiding panics centers around allocations which, though a bit unfortunate, makes sense; it was an intentional design choice to make allocations panic instead of return Results, because most users of the language would probably crash on allocation fails anyways and it would introduce a lot of clutter. There was some effort some while ago on having better fallible allocations, but I'm not sure what happened over there.

#5Does anyone know if there's an obvious reason that adding a `no_panic` crate attribute wouldn't be feasible? It certainly seems like an "obvious" thing to add so I'm hesitant to take the obvious nerd snipe bait.

Author here -- that is surprising. What browser/OS are you on? I haven't had anyone else report this problem before.

#7While not as strict, you can filter lints by their description and apply a policy to your crate

``` [profile.release] panic = 'abort' ```

#9This seems to obviate a lot of Rust's advantages (like a good std library). I wonder what it would take to write a nopanic-std library?
Panics really seem bad for composability. And relying on the optimzer here seems like a fragile approach.
(And how is there no -nopanic compiler flag?)

Same, the web view in my Android client crashed after a couple seconds.
