This:

#declare aVector=<1,2,3,4>;

gets me an error, altough the manual say you can define 4d and 5d vectors.

That's true, but

#declare a = color<1, 2, 3, 4>;

works just fine.  This also works for 5-d vectors.  Maybe it should be
changed, but it was done intentionally, so it's not really a 'bug'.
Apparantly there is a conflict between the program and the documentation,
so one of them needs to be changed.  I personally think that POV should
be changed so you don't need the 'color'.

NOTE:  you could also use rgbf instead of color for 4-d vectors, and
       rgbft for 5-d vectors.
