NAME ^

Syntax::Construct - Identify which non-feature constructs are used in the code.

VERSION ^

Version 0.12

SYNOPSIS ^

For some new syntactic constructs, there is the feature pragma. For the rest, there is Syntax::Construct.

  use Syntax::Construct qw( // ... /r );

  my $x = shift // 'default';
  my $y = $x =~ s/de(fault)/$1/r;
  if ($y =~ /^fault/) {
      ...
  }

DESCRIPTION ^

This module provides a simple way of specifying syntactic constructs that are not implemented via the feature pragma, but are still not compatible with older versions of Perl.

EXPORT ^

Nothing. Using Syntax::Construct with no parameters is an error, giving it an empty list is a no-op.
