# Disable generic_contiguous, as it makes trouble verifying contiguity:
#   - 'contiguous' or '::1' means the dimension is contiguous with dtype
#   - 'indirect_contiguous' means a contiguous list of pointers
#   - dtype contiguous must be contiguous in the first or last dimension
#     from the start, or from the dimension following the last indirect dimension
#
#   e.g.
#           int[::indirect_contiguous, ::contiguous, :]
#
#   is valid (list of pointers to 2d fortran-contiguous array), but
#
#           int[::generic_contiguous, ::contiguous, :]
#
#   would mean you'd have assert dimension 0 to be indirect (and pointer contiguous) at runtime.
#   So it doesn't bring any performance benefit, and it's only confusing.
