Puppet

site.pp:

define x($loglevel) {
}

Produces this error message in the Puppetmaster:

err: Could not parse; using old configuration:  is a metaparameter; please choose another name at site.pp:2
err: undefined method @findclass' for nil:NilClass

Note the lack of information as to what, precisely, is the metaparameter, and the fact that the error is indicated as being on line 2 instead of line 1. By the time you have a half-dozen parameters and a 100 line define, the error message becomes completely unhelpful.

The name of the metaparameter whose turf I’ve infringed on needs to be given, at the very least; fixing the line number would be very helpful too, but I know what racc is like…
