On the Groovy example page there is an example of how to use Groovy HTML builder with mixed content:

p [
        "This is some",
        b"mixed",
        "text. For more see the",
        ahref:'http://groovy.codehaus.org' ["Groovy"],
        "project"
  ]

This is however not working for me, I get an error message like:

expecting ']', found 'mixed' @ line 33, column 23. b"mixed", ^ 1 error 

The Groovy example page states that:

[Note: the syntax in some of these examples is slightly out-dated. See chapter 8 of GINA in the mean-time until these examples are updated.]

My suspicion therefore is that the syntax of the HTML builder has changed, however I don't have the book so I cannot check and I cannot seem to find any relevant example of this working online. Does anyone know how the syntax is supposed to be in Groovy 1.7 and have got this working?
