Declaring Functions AS TYPEs

[TerryRitchie]

So many times I have wished for this:

TYPE TYPE_VECTOR
    x AS SINGLE
    y AS SINGLE
END TYPE

FUNCTION AddVector(v1 AS TYPE_VECTOR, v2 AS TYPE_VECTOR) AS TYPE_VECTOR
    AddVector.x = v1.x + v2.x
    AddVector.y = v1.y + v2.y
END FUNCTION

Or even this would be awesome

DIM v1 AS TYPE_VECTOR
DIM v2 AS TYPE_VECTOR
DIM v3 AS TYPE_VECTOR

v1.x = 10: v1.y = 20
v2.x = 15: v2.y = 15
v3 = v1 + v2

( v3.x now = 25, v3.y now = 35 )

I realize neither of these concepts are in the spirit of QB64, but just imagine.
