+If you prefer to use constants rather than creating empty packages, you can replace the previous example with something like this :
+
+ package MyTypes;
+
+ BEGIN { require Lexical::Types; }
+
+ sub import {
+ my $pkg = caller;
+ for (qw/Str Int/) {
+ my $type = __PACKAGE__ . '::' . $_;
+ no strict 'refs';
+ no warnings 'redefine';
+ *{$pkg.'::'.$_} = eval "sub () { '$type' }";
+ }
+ Lexical::Types->import(
+ as => sub { $_[0] => 'new' }
+ );
+ }
+
+ sub unimport {
+ Lexical::Types->unimport;
+ }
+
+ package MyTypes::Str;
+
+ sub new { ... }
+
+ package MyTypes::Int;
+
+ sub new { ... }
