No, at least not like that. You'd get nothing out of it, even if 
you made it work.

But, I have in the past nested static ifs with different is 
things in order to handle very complex patterns that are 
difficult to express in one.

I can't remember what those are right now though... but if one 
level fails, you might do

static if(is( something ))
   static if(is( details )) {

   }

to drill down. But while I know I have done this before, it is 
rare enough that I cannot recall it!
