NAME

Syntax::Feature::Loop - Provides the loop BLOCK syntax for unconditional loops.

VERSION

Version 1.8.0

SYNOPSIS

    use syntax qw( loop );

    loop {
       ...
       last if ...;
       ...
    }

DESCRIPTION

Syntax::Feature::Loop is a lexically-scoped pragma that provides the loop BLOCK syntax for unconditional loops.

This module serves as a demonstration of the cv_set_call_parser and cv_set_call_checker Perl API calls.

use syntax qw( loop );

use Syntax::Feature::Loop;

Enables the use of loop BLOCK until the end of the current lexical scope.

no syntax qw( loop );

no Syntax::Feature::Loop;

Restores the standard behaviour of loop (a sub call) until the end of the current lexical scope.

loop BLOCK

Repeatedly executes the BLOCK until it is exited using last, return, die, etc.

In other words, it behaves just like all of the following:

  • for (;;) BLOCK

  • while (1) BLOCK

  • while () BLOCK

Like other flow control statements, there is no need to terminate the statement with a semi-colon (;).
