-Pass this method a resultsource name, and an arrayref of
-arrayrefs. The arrayrefs should contain a list of column names,
-followed by one or many sets of matching data for the given columns.
-
-In void context, C<insert_bulk> in L<DBIx::Class::Storage::DBI> is used
-to insert the data, as this is a fast method. However, insert_bulk currently
-assumes that your datasets all contain the same type of values, using scalar
-references in a column in one row, and not in another will probably not work.
-
-Otherwise, each set of data is inserted into the database using
-L<DBIx::Class::ResultSet/create>, and an arrayref of the Result
-objects is returned.
-
-e.g.
-
-  $schema->populate('Artist', [
-    [ qw/artistid name/ ],
-    [ 1, 'Popular Band' ],
-    [ 2, 'Indie Band' ],
-    ...
-  ]);
-
-Since wantarray context is basically the same as looping over $rs->create(...)
-you won't see any performance benefits and in this case the method is more for
-convenience. Void context sends the column information directly to storage
-using <DBI>s bulk insert method. So the performance will be much better for
-storages that support this method.
-
-Because of this difference in the way void context inserts rows into your
-database you need to note how this will effect any loaded components that
-override or augment insert.  For example if you are using a component such
-as L<DBIx::Class::UUIDColumns> to populate your primary keys you MUST use
-wantarray context if you want the PKs automatically created.
+A convenience shortcut to L<DBIx::Class::ResultSet/populate>. Equivalent to:
+
+ $schema->resultset($source_name)->populate([...]);

+=item NOTE
+
+The context of this method call has an important effect on what is
+submitted to storage. In void context data is fed directly to fastpath
+insertion routines provided by the underlying storage (most often
+L<DBI/execute_for_fetch>), bypassing the L<new|DBIx::Class::Row/new> and
+L<insert|DBIx::Class::Row/insert> calls on the
+L<Result|DBIx::Class::Manual::ResultClass> class, including any
+augmentation of these methods provided by components. For example if you
+are using something like L<DBIx::Class::UUIDColumns> to create primary
+keys for you, you will find that your PKs are empty.  In this case you
+will have to explicitly force scalar or list context in order to create
+those values.
