Incorrect token type given to some resource attributes

[alexjfisher]

If the name of a resource attribute clashes with a Puppet keyword, then puppet-lint does not assign it the :NAME token type, but a keyword token type instead.

For example, with this Exec resource

exec { '/bin/some_command':
  unless => '/bin/foo',
}

The unless bare word is assigned the :UNLESS token type. Since in this context, it is not the unless puppet keyword, it should be assigned the :NAME token type instead.

This also causes issues when using resource_indexes. The :param_tokens hash element for the above example is an empty array, when it should contain a single token (for the single attribute used).

From http://puppet-lint.com/developer/api/

:param_tokens - An Array of PuppetLint::Lexer::Token objects for the parameter names in the resource declaration.
