Jira (PUP-4193) Add pattern matching to the Puppet DSL

[David Lutterkort (JIRA)]

Title: Message Title

David Lutterkort commented on PUP-4193   Re: Add pattern matching to the Puppet DSL Full pattern matching in e.g. OCaml also allows variable binding and adding conditions based on those variables; there what you describe above, would look more like case [value1, value2] { [ $x, $y ] when (is_special($x) && (is_interesting($y) || is_special($y)) : { } } I think that moving the condition into a when clause makes it easier to understand how variables are picked out and what the precise condition is. It also makes it possible to have conditions involving both $x and $y. In OCaml, pattern matching can also be used to destructure data; have a look at this page especially the drop_zero example. I don't think though we need something that complex (yet) Add Comment   This message was sent by Atlassian JIRA (v6.3.15#6346-sha1:dbc023d) -- You received this message because you are subscribed to the Google Groups "Puppet Bugs" group.
