Error handling and multi loop exiting are permitted use cases of go-to.
Java doesn’t allow goto, but specifically does have labels for labeled break/continue to support the multi-loop exiting case.
I imagine these two “structures” will always be implemented in C source through disciplined use of goto.
It’s literally the only way to do this. Other ways include checking of loads of bools. That’s slow.
In C maybe. In language that support proper recursion schemes, the apomorphism models the early-exit loop.
IIRC, this is because gcc optimizes goto very well, or at least it did back in the day. It also is a genuinely workable solution for error handling in C.
Consider if you need to setup three things, do something with them, and then tear them down in reverse order. If there’s an error on the second thing, you want to jump right to the part where you tear down the first thing. Using goto tends to make cleaner code for that in C compared to, say, nested conditionals.
but how many COMEFROMs are there
It’s beautiful
Really nice combination of data and presentation.
~200000 in ~73 million isn’t so bad, right?
I’m pretty certain this has traumatized me.
