The solution that Doug showed works now...  I guess you mean the 
"eval(foo)" and "subs(foo)" approach that will be in Symbolic 2.8.0.

Symbolic 2.8.0 will be released soon after SymPy 1.4, likely within a 
month or so.

Some testing of subs/eval stuff would be great: feel free to download 
and try it before the release.
