Syntax::Construct - Identify which non-feature constructs are used in the code.
Version 0.08
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/) { ... }
Nothing. Using Syntax::Construct with no parameters is an error, giving it an empty list is a no-op.
