#declare TransA = transform {rotate x*30}
#declare TransB = transform {scale <1,.5,1> translate x*10 rotate y*60}
#declare InvTrans =
transform {
    transform {TransA}
    transform {TransB}
    inverse
}

#declare MyObject=
box { 0, 1
    transform {TransA}
    texture { Whatever }
    transform {TransB}
}

Using the additional syntax of my patch, of course.
