Yes, clearly. The only difference is that an extra comma is required,
as in:
----v
throw Exception => "Can't foo.", tag => "ABC.1234";
sub throw
{
my ($C, $msg, %opts) = @_;
die $C->new($msg, %opts) unless ref $C;
die $C if $C->isa("Exception");
die new Exception::NotException "...",
debug => join(", ", @_);
}
And, who knows what syntax options will be available with Perl 6?
