7

SYNOPSIS

9       See instead Syntax::Keyword::Defer.
10
11          use Syntax::Keyword::Defer;
12
13          {
14             my $dbh = DBI->connect( ... ) or die "Cannot connect";
15             defer { $dbh->disconnect; }
16
17             my $sth = $dbh->prepare( ... ) or die "Cannot prepare";
18             defer { $sth->finish; }
19
20             ...
21          }

DESCRIPTION

24       This module provides a syntax plugin that implements a phaser block
25       that executes its block when the containing scope has finished. The
26       syntax of the "FINALLY" block looks similar to other phasers in perl
27       (such as "BEGIN"), but the semantics of its execution are different.
28
29       The keyword has now been renamed to "defer" but is otherwise identical
30       to the syntax and semantics that were provided here. This module
31       currently provides a back-compatibility layer.
32
33       This will be removed in a later version. You should change any code
34       currently using it, to Syntax::Keyword::Defer instead.
