More seriously, a decent commentary on how to use goto "correctly" would be
a nice thing to see.
Here you go, just in case you missed it the first time I posted

Another thing that makes me incredibly dubious about some of the
opinions in these videos is the hackneyed nonsense about "goto
considered harmful". The original paper was misunderstood in that all
goto statements are harmful and brainwashed a generation. Some of these
videos present a trivial

It's like any dogma, if you want to believe then you will. If you have

have enterprise support where you can use SMP/E.

Another example is the pthread library which uses a naming convention
that describes the context it's operating on. For example,
pthread_mutex_lock, pthread_cond_wait etc. I've used this kind of naming
convention myself but I only write Metal/C these days and C++ when using
LE.
