$normal_user☠ Perl
Lorzy:Lazy, Lispy, Orz
• Scheme-like interpreter in Perl
• Typeful
• uses Moose & Moose type system
Example
Defining Rules, Actions
(Think gmail filters)
(lambda (ticket transaction) <HERE>) :: Bool
sub { my ($ticket, $transaction) = @_; <HERE> }# returns Bool
If ticket’s queue matches “Foo”
$ticket->queue->name eq “Foo”
S-Expression
(Str.Eq (RT::Model::Queue.name (RT::Model::Ticket.queue ticket)) “Foo”)
Strongly Typed
(Types are Good)
Problem
$ticket->queue->name eq “Foo”
$ticket->queue->name eq “Foo”
$ticket->queue->name eq “Foo”
$ticket->queue->name eq “Foo”
???!!!
Type mismatch!
