Methods on evaluations page syntax incorrect

 "$session.myTextAsMonogram": "[[$self.text:monogram]]",
 "$session.myTextTruncated": "[[$self.truncate(5)]]",
 "$session.myTextAsUppercase": "[[$self.uppercase]]"

These methods use dot instead of colon syntax in the documentation, which does not appear to work. Using colon syntax does work.
