"length" is a reserved word. You have to change that.

On the wiki for StringTemplate 3.0 documentation, see the bottom of the
"StringTemplate cheat sheet" section, which lists all the ST reserved
words.

TODO: Put "Reserved Words" in its own section. This is really important,
and bit me the other day too. I know its really short, but it's really
important, so there's no reason to not give it its own section with a
top-level heading, so people can easily click on it. Perhaps with a link
inside the "cheat sheet" page.
