so I misunderstood... it was not, that somehow body was not recognized
as closure or such, it is that the execution of code inside fails.
capitalize() is a method on CharSequence, StringWriter is no
CharSequence, so the call fails. Did you add such a method yourself? if
not, you need to convert to String first.
