Well, there a many possibilities ... depends on purpose
Use an abbreviation for instance:
(1) -> assign(var,val) ==> var:=val
Type: Void
(2) -> assign(x,10)
(2) 10
Type: PositiveInteger
(3) -> x
(3) 10
Type: PositiveInteger
(4) -> assign(u,y^2+z^2)
2 2
(4) z + y
Type: Polynomial(Integer)
(5) -> u
2 2
(5) z + y
Type: Polynomial(Integer)
Or in macro notation:
(6) -> macro myass(a,b) == a:=b
Type: Void
(7) -> myass(t,z)
(7) z
Type: Variable(z)
(8) -> t
(8) z
Type: Variable(z)
