Not sure if this qualifies as simple but you can use callCC to force an
exit from within an inner call. In this example we call f which calls f1
which calls f2 and then f2 exits right out to the top level returning 0.
Note that f2 must know about g:
f <- function(g) {
f1 <- function() {
cat("A\n")
f2()
cat("B\n")
}
f2 <- function() {
cat("a\n")
g(0)
cat("b\n")
}
f1()
}
callCC(f)
