When translate the template code to D code,  need a lot D type 
arguments information.  And one Web application may need very 
many page,  and the type may change frequently.  If I am not 
doing it on the CTFE will geometric increase workload.

If D want to be participants in the web field,  I think that this 
feature sooner or later will be needed.
