I was curious if this was still true today (the post was

Thanks!
I don't remember that the invariant was ever called in release
mode. But maybe I'm not understanding the statement.

I think what he was saying was that even in release mode, the
druntime would keep the invariant "subsystem," but just wouldn't
call the invariant handlers. So even in release mode, the code
to get a list of all handlers would happen, they just wouldn't be
invoked. Rather than completely ripping out the invariant system.
