Comment:
Can this ticket be closed? The specific feature it was asking for now
(sort of) exists:
{{{
sage:
var('x,y,z');VS=VectorSpace(CallableSymbolicExpressionRing((x,y,z)),2)
(x, y, z)
sage: VS.an_element()
(x, y, z) |--> (1, 0)
}}}
and work on various kinds of tensor fields is ongoing as part of
SageManifolds (#14865, #15916).
