soya3d is using these pretty nicely for 3d:
(from the tutorial/basic-4.py, available from
http://home.gna.org/oomadness/en/soya/index.html)
# Lots of Soya methods have also an operator :
#
# Position + Vector => Point
# Position += Vector Position.add_vector(Vector)
# Position >> Position Position.vector_to (Position) => Vector
# Position %= CoordSyst Position.convert_to(CoordSyst)
# Vector * float
# Position + Vector => Point
# Position += Vector
# Position.add_vector(Vector)
# Translation or vectorial addition (if the Position is a Vector).
# Position >> Position => Vector
# Position.vector_to (Position) => Vector
# Creates a vector from a strating and an ending position.
# Position %= CoordSyst Position.convert_to(CoordSyst)
# Vector * float
