## Labeled Loop

Support labeled loop and escape from nested loop

# LabeledLoop

A simple package for R providing a support for labeled loop. The semantics is similar with Java's labeled loop. The labeled loops can be nested.

Here is a basic example:

. %._.% for(i in 1:3) {
foo %._.% for (j in 1:3) {
orz %._.% for (k in 1:3) {
print(c(i, j, k))

if (i == 3 && j == 3 && k == 2) {
cat("escape from outmost loop\n")
._.() # break
}

if (i == 2 && j == 2) {
cat("escape from innermost loop (orz)\n")
._.(orz) # break
}

if (i == 1 && j == 1 && k == 2) {
cat("escape from foo\n")
._.(foo) # break
}
}
}
}


Then, the output looks like:

[1] 1 1 1
[1] 1 1 2
escape from foo
[1] 2 1 1
[1] 2 1 2
[1] 2 1 3
[1] 2 2 1
escape from innermost loop (orz)
[1] 2 3 1
[1] 2 3 2
[1] 2 3 3
[1] 3 1 1
[1] 3 1 2
[1] 3 1 3
[1] 3 2 1
[1] 3 2 2
[1] 3 2 3
[1] 3 3 1
[1] 3 3 2
escape from outmost loop
