SYNOPSIS

13           use syntax qw( loop );
14
15           loop {
16              ...
17              last if ...;
18              ...
19           }

DESCRIPTION

22       Syntax::Feature::Loop is a lexically-scoped pragma that provides the
23       "loop BLOCK" syntax for unconditional loops.
24
25       This module serves as a demonstration of the "cv_set_call_parser" and
26       "cv_set_call_checker" Perl API calls.
27
28   "use syntax qw( loop );"
29   "use Syntax::Feature::Loop;"
30       Enables the use of "loop BLOCK" until the end of the current lexical
31       scope.
32
33   "no syntax qw( loop );"
34   "no Syntax::Feature::Loop;"
35       Restores the standard behaviour of "loop" (a sub call) until the end of
36       the current lexical scope.
37
38   "loop BLOCK"
39       Repeatedly executes the BLOCK until it is exited using "last",
40       "return", "die", etc.
41
42       In other words, it behaves just like all of the following:
43
44       ·   "for (;;) BLOCK"
45
46       ·   "while (1) BLOCK"
47
48       ·   "while () BLOCK"
49
50       Like other flow control statements, there is no need to terminate the
51       statement with a semi-colon (";").
