Never seen the Linux Kernel source code?
Sometimes goto statements can make the code more efficient, cleaner and concise.

Linus about the use of goto's:

Quote:
I think goto's are fine, and they are often more readable than large
amounts of indentation. That's _especially_ true if the code flow isn't
actually naturally indented (in this case it is, so I don't think using
goto is in any way _clearer_ than not, but in general goto's can be quite
good for readability).

Of course, in stupid languages like Pascal, where labels cannot be
descriptive, goto's can be bad. But that's not the fault of the goto,
that's the braindamage of the language designer.

Linus

ppi::statement::break

PPI::Statement::Break(3)				User Contributed Perl Documentation				  PPI::Statement::Break(3)

NAME

       PPI::Statement::Break - Statements which break out of normal statement flow

SYNOPSIS

	 last;
	 goto FOO;
	 next if condition();
	 return $foo;
	 redo;

INHERITANCE

	 PPI::Statement::Break
	 isa PPI::Statement
	     isa PPI::Node
		 isa PPI::Element

DESCRIPTION

       "PPI::Statement::Break" is intended to represent statements that break out of the normal statement flow control. This covers the basic
       types 'redo', 'goto', 'next', 'last' and 'return'.

METHODS

       "PPI::Statement::Break" has no additional methods beyond the default ones provided by PPI::Statement, PPI::Node and PPI::Element.

       However, it is expected to gain methods for identifying the line to break to, or the structure to break out of.

TO DO

       - Add the methods to identify the break target

       - Add some proper unit testing

       See the support section in the main module.
