Feature #4598: fail should be usable in a selector
http://projects.puppetlabs.com/issues/4598

Author: Alan Barrett
Status: Needs design decision
Priority: Normal
Assignee: Luke Kanies
Category: metaparameters
Target version: 
Affected version: 
Keywords: 
Branch: 


It would be nice if this worked better:
<pre>
notify { "test":
    message => $environment ? {
        production => "http://blah/blah/prod";,
        development => "http://blah/blah/dev";,
        default => fail("environment '${environment}' is not yet supported"),
    }
}
</pre>

Desired result when the default branch of the selector is taken:  Failure to 
compile the catalog, with the error message "environment 'foo' is not 
supported".

Actual result when the default branch of the selector is taken:  Failure to 
compile the catalog, with the error message "Function 'fail' does not return a 
value".

Use case:  Downloading an environment-dependent URL on the client.
