tbh i don't know Go too well. as i understand it, `panic` can indeed hijack the control flow, i.e. stop it. but any function¹ can do that: just do `while 1 {}`! control flow won't return to the caller either way. so it's not that weird after all

Ruby blocks can do non-local control flow, i.e. return from their surrounding function, but that's what makes them distinct from functions.

(i'm a Haskell enthusiast, so please excuse the nitpicking :)

A panic can be recovered with recover(), and thus the program can continue. While a function that does an infinite loop will halt the program and nothing else.
