Well, not on this list, I guess...

Looks like most or all of your examples would be unnecessary if
you had exception handling and garbage collection. Conversely,
after many years of programming in Java, I can't remember a time
where I needed or wanted to use a goto.
In C, I would very often have a label at the end of a function
that would test various pointer variables and free them if they
were non-null. But that's not required if you don't have to
explicitly free anything, and if there is cleanup to be done explicitly,
there's always the finally block.
