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.
