thinking about a programming language feature i really want and realizing that its just goto

I don't, however, find gotos particularly useful in practice once you have gained the knowledge of how CPU jumps work. Furthermore, CPU jumps require some additional education, such as what macro-op fusion is and why you should make sure the loops you write can use it.

This is something of a challenge, as what is macro-fusable differs quite a bit between architectures (and implementations of architectures). It’s good to be aware of, however.
