\begin{MIntro}
  \eng{
The {\Mthis} function tests whether \Mex{expr} is a skew partition that is a
a list with two components \Mex{l1} and \Mex{l2}, \Mex{l1} being the exterior
shape, \Mex{l2} the interior shape.
The diagram of bixes needs not to be connected, the condition being that the
diagram of \Mex{l2} must be included into the one of \Mex{l1}.
