STRICTMULTIASSIGNMENT would detect most cases of this, except that
the condition is checked too late.  We'd need to count the fields
*before* trying to assign values, not after.

In the meantime, it does seem like the docs could be more explicit
about this, and perhaps give an example showing the (x).* solution.
