No, there is no limit on the dimension of the matrix, but lst() is a call
to a constructor and we can only have a finite number of such
precompiled ctors.  We have to draw a line somewhere.  We chose to draw
it at 16, because 4x4 matrices were rather natural and important.

Just don't create your matrices like this if you need bigger ones.  Have a
look at the check directory and how large matrices are created in there
for inspiration.  Particularly, the Lewis-Wester test O, M1, M2 and maybe
some others.
