I don't use it, but forgot about your mention of parametric...

I'm not sure why so slow either though suppose we should expect it to be 
3x slower as a sort of baseline. Never looked at it with any of the 
performance tools. Next time I have a compile set up for profiling I'll 
try to remember to run a parametric or two. Maybe something will pop out.

I've dug a little into parametric shadow issues. I think Jerome has a 
github issue open on the parametric for something similar. Didn't dig 
deep, but looked to me like the code only returns one root which can be 
an problem for shadows.
