The intended use is as a variable name. When assigned, it is simply skipped. This is useful in a lambda where the function feeds values into the lambda that are not going to be used, and (as discussed in PUP-4193) as a wildcard in pattern matching.\r\n\r\nThe work is to compare how variables like this is used in other languages and how this can be applied/made useful in the Puppet Language."}}
