Dear PSTricks maintainers,

Could you implement the radii of \psRing to also accept postfix expression?
\pscircle radius can accept postfix expression, in my humble opinion,  \psRing also needs such a feature. 

\documentclass[pstricks,border=12pt]{standalone}

\begin{document}
\begin{pspicture}[showgrid](-3,-3)(3,3)
\psRing*[linecolor=red,opacity=.5](0,0){2}{3}
\psRing*[linecolor=blue,opacity=.25](0,0){!1}{!1.5}% <=== does not work
\end{pspicture}
\end{document}


Thank you in advance.


best regards,
