I have tried with commas

use strict;
use warnings;

use Email::Send::SMTP::Gmail;

my $mail=Email::Send::SMTP::Gmail->new( -smtp=>'smtp.gmail.com',
                    -layer=>'ssl',
                                        -port=>465,,
                    -verbose => '1',
                    -login=>'mylogin',
                    -pass=>'mypassword');

$mail->send(-to=>'toaddress',
        -subject=>'Hello!',
        -verbose=>'1',
        -body=>'Just testing it',
        -attachments=>'');

$mail->bye;

The documentation of the module is a bit confused, but the usage in the documentation is:

I'm not sure why you're getting the error as the first argument. The real cause for the error is still in the message. Maybe you should read it.
