- next LABEL

- next EXPR
- next

  The `next` command is like the `continue` statement in C; it starts the next iteration of the loop:

          LINE: while (<STDIN>) {        next LINE if /^#/;  # discard comments        #...    }

  Note that if there were a `continue` block on the above, it would get executed even on discarded lines. If LABEL is omitted, the command refers to the innermost enclosing loop. The `next EXPR` form, available as of Perl 5.18.0, allows a label name to be computed at run time, being otherwise identical to `next LABEL` .

  `next` cannot be used to exit a block which returns a value such as `eval {}` , `sub {}` , or `do {}` , and should not be used to exit a grep() or map() operation.

  Note that a block by itself is semantically identical to a loop that executes once. Thus `next` will exit such a block early.

  See also continue for an illustration of how `last`, `next`, and `redo` work.

  Unlike most named operators, this has the same precedence as assignment. It is also exempt from the looks-like-a-function rule, so `next ("foo")."bar"` will cause "bar" to be part of the argument to `next`.
