[pstricks] Raw postscript code in pnode

[John Smith]

Is there a way to include raw postscript in the nodesep argument of pnode?

Here's an example:

\pspicture(0,10)(0,10)

\SpecialCoor
\pnode(1,1){A}
\pnode([nodesep=!2 2 mul,angle=2]A){B} % this causes an error
\pnode([nodesep=2,angle=!2 2 mul]A){B} % this is ok

\endpspicture

Why is raw postscipt ok in angle but not nodesep?

Thanks.
