From the docs:

vrotate(A,B) 
Rotate A about origin by B. 
Given the x,y,z coordinates of a point in space designated 
by the vector A, rotate that point about the origin by an 
amount specified by the vector B. Rotate it about the x-axis 
by an angle specified in degrees by the float value B.x. 
Similarly B.y and B.z specify the amount to rotate in degrees 
about the y-axis and z-axis. The result is a vector containing 
the new x,y,z coordinates of the point.


A contains a point reference
B contains a rotation reference.
The function vrotate(A,B) returns the new point reference 
if you rotate point A by rotation B.

i.e. point{<0,0,0> translate A rotate B}

I know that there is no object called point{ <location>
[OBJECT_MODIFIERS...] }
but it does help to use it in this way with translate and rotate .
