[Bioperl-l] Allowing a list of ids for -id of Bio::DB::EUtilities->new()?

[Fields, Christopher J]

It does allow multiples, note Russell’s example (note it has to be passed as a reference).  

my @ids     = qw(200039684 200039685);
my $factory = Bio::DB::EUtilities->new(-eutil  => 'elink',
                                      -email  => 'mymail at foo.bar',
                                      -db     => 'pubmed',
                                      -dbfrom => 'gds',
                                      -id     => \@ids);

The ‘single ID’ form is a convenience; the fact it works when you concatenate the IDs and pass them in as one string is happenstance, only b/c it’s doing that for you behind the scenes when you pass the IDs as a ref.
