The least squares module is not really a part of MMTK; it's part of
a collection of general science modules, which happens to be used by

That's exactly the right thing to do. I put in those tuple() conversions
for some testing and forgot to take them out again before releasing
the module...

With your fix it *will* work with multivariate model functions.
