594	UndefinedError if output from template function is wrapped in tuple	fschwarz	cmlenz	"This template causes an exception: ""{{{UndefinedError: ""name"" not defined}}}""

{{{
#!xml
<doc xmlns:py=""http://genshi.edgewall.org/"">
   <py:def function=""foo(name)"">__${name}__</py:def>
   ${tuple(foo('bar'))}
</doc>
}}}

Once the 'tuple()' is removed everything works as expected. I found the error message very confusing as undefined variables don't have anything to do with return values of a function.
