newfunction(:reject, :type => :rvalue, :doc => <<-EOS) do |args|
This function searches through an array and rejects all elements that match
the provided regular expression.
*Examples:*
reject(['aaa','bbb','ccc','aaaddd'], 'aaa')
Would return:
['bbb','ccc']

if (args.size != 2)
raise Puppet::ParseError,
"reject(): Wrong number of arguments given #{args.size} for 2"
end
ary = args[0]
pattern = Regexp.new(args[1])
