You are right. I tried making one. It parses things like sum !(q{  i=0:10; 
i * sum!(q{   j=0:10, j!=i;    i*j   })  })

But it doesn't work because not being CTFE friendly, and also syntax parser 
is ugly because I am not strong at syntax parsing.
Note that creating good syntax parser in CTFE is rather hard, especially for 
complex syntaxes like of D expressions.
Oh, if CTFE could:
 1) run external process
 2) do file i/o
 3) use dynamic libraries
This would be much much simpler, but I guess it will not.
This features also has safety issues, but D is system language, not browser 
one.
