CFEngine 3.3.5 does not like {{{ classes: "webclass" or => { "@(webservers)" }; }}} (Was: Re: CFEngine Help: Re: False report of "no constrants" in constrained classes promises.)

Dear Mark,

  I tried the above, and it works standalone, but when I tried to
integrate it into Neil Watson's dynamic bundlesequence example
(http://watson-wilson.ca/2011/09/dynamic-bundlesequence-in-cfengine.html)
I got: Unable to parse class expression: ->@(webservers)

This is with 3.3.5.  Please advise?
