No, I have not. Though a year or so ago there was a discussion about this
in distutils list, mainly for adding Fortran compiler support to
distutils. At the time I didn't have resources to push scipy_distutils
features to distutils and even less so for now. So, one can think that
scipy_distutils is an extension to distutils, though it also includes
few bug fixes for older distutils.
On the other hand, since Scipy supports Python starting at 2.2 then it
cannot relay much on new features added to distutils of later Python
versions. Instead, if these features happen to be useful for Scipy then
they are backported for Python 2.2 through implementing them in
scipy_distutils. "Luckily", there are not much such features as
scipy_distutils has evolved with new very useful features much quicker
But, for Numeric3, scipy.distutils would be a perfect place to clean up
scipy_distutils a bit, e.g. removing some obsolete features and assuming
that Numeric3 will support Python 2.3 and up. Based on that, integrating
scipy_distutils features to standard distutils can be made less pain if
someone decides to do that.
