TWiR quote of the week

[Cerber-Ursi]

vector[10] desugars to a function call <Vec as std::ops::Index>::index(&vector, 10) , which in this case panics, but it could as well play a song and return -1 on out of bounds access.

However, the safety — at run time — is still guaranteed.

Undefined behaviour never was so nice! (Yes, I know that it's well defined by implementation, but doesn't this sound like it?)
