Description
Panicking is almost completely undocumented. How much of this is relevant to the reference and how much is implementation-specific? At the very least, something should define what "panic" is, since it is referred to in a few places. I feel like there is lots to be said about panicking, but it's hard for me to say specifically.
One example is to document panic behavior with extern functions: rust-lang/rust#55982.
