Subject: [PATCH] gnu: Add python-numpy-2.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Test suite for NumPy@2.2.2 is heavily depends on included vendored-meson
sub-package and all of the tests fail.  This variant provides a working
NumPy, with passed build and sanity-check phases and tests disabled; it
allows users to include it in other package(s) where version 2+ is hard
required e.g. SageMath or Astropy@7.

* gnu/packages/python-xyz.scm (python-numpy-2): New variable.
