[pstricks] Nodes and \rput

[Michael Sharpe]

\rput doesn't seem to translate positions involving nodes. For example,

\begin{pspicture}(6,6)
\pnode(1,1){P}
\rput(2,3){\psline(1,1)}% makes line from (2,3) to (3,4)
\rput(2,3){\psline(P)}% makes line from (2,3) to (1,1)
\end{pspicture}

Is this something that can be changed by evaluating the expression in  
another way? It doesn't seem to help to replace \psline(P) by  
\psline(! \psGetNodeCenter{P} P.x P.y).
