The returned value\nMUST be rendered against the default delimiters, then interpolated in place\nof the lambda.\n\nWhen used as the data value for a Section tag, the lambda MUST be treatable\nas an arity 1 function, and invoked as such (passing a String containing the\nunprocessed section contents).
