geometric operations on QML `point` type

Question

Consider a variable of type point: it doesn't seem to have the same methods as vector2d.

E.g.:

readonly property point distance: pos.minus(referencePos).length()

and also there are no conversion functions from point to vector2d.

This does not work:

Qt.vector2d(pos)

Error: Qt.vector2d(): Invalid arguments

So for a typical geometrical operation on points one has to do:

readonly property point distance: Qt.vector2d(pos.x, pos.y).minus(Qt.vector2d(referencePos.x, referencePos.y)).length()

in my opinion exceedingly long and repetitive. I would end up making a library of functions to cut the noise to minimum.

Or am I missing something?

So what's the recommended pattern? Expose properties as point and internally convert to vector2d?
