Cannot multiply Mat3 and Vec3

Would it be possible to support this?

I see code similar to this work in glsl code online:

var n = normalize(mat3(transformMatrix) * input.position);

But I get Cannot multiply Mat3 and Vec3.
Or is there a different way to make this work?

Does input.position * mat3(transformMatrix) work? I think I encounted it a while ago, and it was due to argument ordering, as A op B not always implies B op A in HXSL.

Ah, yes that seems to work. Would be nice if it works both ways.
