I'm surprised no-one has requested the LU decomposition in NumPy
before -- it is a fundamental building block in linear algebra.  I
think it is going too far, stating that NumPy's linear algebra module
serves simply as an upgrade path for those coming from Numeric.  Its
use has developed far beyond that.

I'd rather we examine each function on a case-by-case basis, than to
put a solid freeze on NumPy.
