Where?  I even looked through the code in DT_In.py and couldn't
figure out where it handled this special case.  This seems
to me like a pretty big gotcha.

I did find out that a list of two items was not handled
the same way as a tuple of two items.  Unfortunately
I couldn't figure out how to invoke list().

Well, the only solution I came up with was to iterate
with an index over the size of the thing.
