I found this funny.

The context is as explained by @laund@hachyderm.io

the issue is that you can't return from inside a closure, since the closure might be called later/elsewhere

and this post was the asnwer to the question by @antonok@fosstodon.org

you got me curious what the record for the longest ? operator chain on crates.io is

Runtime or compile-time? If run-time, that sounds like a fun way to implement something like panic().

runtime, the point is so that you can see if the types align and then come back and fill in the function bodies later
