EXAMPLE1

 use strict;
 use warnings;

 use Wikibase::Datatype::Utils qw(check_entity);

 my $self = {

 };
 check_entity($self, 'key');

 # Print out.
 print "ok\n";

 # Output:
 # ok

EXAMPLE2

 use strict;
 use warnings;

 use Error::Pure;
 use Wikibase::Datatype::Utils qw(check_entity);

 $Error::Pure::TYPE = 'Error';

 my $self = {
         'key' => 'bad_entity',
 };
 check_entity($self, 'key');

 # Print out.
 print "ok\n";

 # Output like:
 # #Error [/../Wikibase/Datatype/Utils.pm:?] Parameter 'key' must begin with 'Q' and number after it.

EXAMPLE3

 use strict;
 use warnings;

 use Wikibase::Datatype::Utils qw(check_lexeme);

 my $self = {
         'key' => 'L123',
 };
 check_lexeme($self, 'key');

 # Print out.
 print "ok\n";

 # Output:
 # ok

EXAMPLE4

 use strict;
 use warnings;

 use Error::Pure;
 use Wikibase::Datatype::Utils qw(check_lexeme);

 $Error::Pure::TYPE = 'Error';

 my $self = {
         'key' => 'bad_entity',
 };
 check_lexeme($self, 'key');

 # Print out.
 print "ok\n";

 # Output like:
 # #Error [/../Wikibase/Datatype/Utils.pm:?] Parameter 'key' must begin with 'L' and number after it.

EXAMPLE5

 use strict;
 use warnings;

 use Wikibase::Datatype::Utils qw(check_property);

 my $self = {
         'key' => 'P123',
 };
 check_property($self, 'key');

 # Print out.
 print "ok\n";

 # Output:
 # ok

EXAMPLE6

 use strict;
 use warnings;

 use Error::Pure;
 use Wikibase::Datatype::Utils qw(check_property);

 $Error::Pure::TYPE = 'Error';

 my $self = {
         'key' => 'bad_property',
 };
 check_property($self, 'key');

 # Print out.
 print "ok\n";

 # Output like:
