      A regression in hiera 5 caused an error to not be issued when calls to any of the hiera_* functions contained an unescaped period {{.}} in the requested key. There is no such restriction when the {{lookup}} function is used. The regression caused silent undefined behavior. This is now fixed and the earlier behavior of the hiera_* functions have been restored.

      Description

      We are in tihe process of moving to puppet 4. One of the issues we encountered with puppet 4.8.2 (puppet-agent 1.8.3) was that when trying to read a hash from hiera that contained a dot in the name. We used 4.8.2 first as 4.9.3 was giving us a lot of issues. However, with the release of 4.9.4, most were fixed so we switched to that. However, I noticed a regression has slipped in where hashes with dots in the name are no longer failing a puppetrun. In fact, they are silently ignored (leaving your resources unmanaged!). The puppetserver also doesn't print any warning about using illegal hash names.

      Example hash that should fail:

      my.hash:
      		 
        some: value
      		 
        another: value

      With puppet 4.8.x, reading this hash with hiera_hash fails the run with:

      Evaluation Error: Error while evaluating a Function Call, Resolution type :hash is illegal when accessing values using dotted keys. Offending key was ....
