Re: Typing local variables does not work - results in Error: This Type-Name has no effect Thank you very much for the thorough explanation, Henrik Lindberg! I missed this key portion of the documentation where the use cases for data types are listed: https://docs.puppetlabs.com/puppet/latest/reference/lang_data_type.html#usage

No problem. I did write it up a bit longer than usual because this sounded like a corner others would paint themselves into as well and it is not unreasonable at all, given how you do typing in other programming languages that an expression like String $x = something would type the variable $x. I did change the title to make it more googlable (is that even a word?).

I came across this issue while investigating a different problem and just wanted to clarify.  first, thanks Henrik Lindberg for the great explanation however i believe the following needs clarifying Puppet 4.x does not support typing variables. Type aliases where introduced in puppet 4.4 so i think this should read "Puppet < 4.4.0 does not support typing variables.

@john Not quite - typing variables have never been supported - parameters can be typed though (as explained above).

Henrik Lindberg thanks i hadn't noticed that the variable in `vartest::params` was not a parameter
