 +
 +Pass an arrayref of hashrefs. Each hashref should be a structure suitable for
 +submitting to a $resultset->create(...) method.
 +
 +In void context, C<insert_bulk> in L<DBIx::Class::Storage::DBI> is used
 +to insert the data, as this is a faster method.
 +
 +Otherwise, each set of data is inserted into the database using
 +L<DBIx::Class::ResultSet/create>, and a arrayref of the resulting row
 +objects is returned.
 +
 +Example:  Assuming an Artist Class that has many CDs Classes relating:
 +
 +  my $Artist_rs = $schema->resultset("Artist");
 +  
 +  ## Void Context Example 
 +  $Artist_rs->populate([
 +     { artistid => 4, name => 'Manufactured Crap', cds => [ 
 +        { title => 'My First CD', year => 2006 },
 +        { title => 'Yet More Tweeny-Pop crap', year => 2007 },
 +      ],
 +     },
 +     { artistid => 5, name => 'Angsty-Whiny Girl', cds => [
 +        { title => 'My parents sold me to a record company' ,year => 2005 },
 +        { title => 'Why Am I So Ugly?', year => 2006 },
 +        { title => 'I Got Surgery and am now Popular', year => 2007 }
 +      ],
 +     },
 +  ]);
 +  
 +  ## Array Context Example
 +  my ($ArtistOne, $ArtistTwo, $ArtistThree) = $Artist_rs->populate([
 +    { name => "Artist One"},
 +	{ name => "Artist Two"},
 +	{ name => "Artist Three", cds=> [
 +	  { title => "First CD", year => 2007},
 +	  { title => "Second CD", year => 2008},
 +	]}
 +  ]);
 +  
 +  print $ArtistOne->name; ## response is 'Artist One'
 +  print $ArtistThree->cds->count ## reponse is '2'
