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.

By coincidence, Walter recently mentioned something similar being integrated into D to support DStep:
http://forum.dlang.org/post/jta97l$10hm$1@digitalmars.com

So perhaps the above mixin would be:
import "template_file_path.htm";

According to the link, that would execute:
htm_to_D template_file_path.htm

The htm_to_D program would generate a .d module which would then get imported.
