Bug #18672: Cannot use empty hash literal in case statement
https://projects.puppetlabs.com/issues/18672#change-81220

Author: Andrew Parker
Status: Accepted
Priority: Normal
Assignee: 
Category: language
Target version: 
Affected Puppet version: 2.7.19
Keywords: language parser
Branch: 


As reported by Peter Bauer on the puppet-dev mailing list 
(<https://groups.google.com/forum/#!msg/puppet-dev/bYF1XMKPZ2M/nGNl_-5K1nEJ>), 
the following code will produce a parse error:
<pre>
$boole = true
$testvar = $boole ? {
  true => {},
  default => { hans => franz },
}
</pre>

The error:
<pre>
Could not parse for environment production: Syntax error at '{'; expected '}' 
at /tmp/test.pp:3
</pre>

An even simpler example is:
<pre>
> puppet apply -e "notify(true ? { true => {} })"
Error: Could not parse for environment production: Syntax error at '{'; 
expected '}' at line 1 on node aparker.corp.puppetlabs.net
Error: Could not parse for environment production: Syntax error at '{'; 
expected '}' at line 1 on node aparker.corp.puppetlabs.net
</pre>
