reflection based on my experience so far on compile-time meta-programming in D as a novice user: the problems

The point I want to make is: all the supposed high level fancy D 
mechanisms are too complex to use (or may not even made to work 
at all, I'm not sure).

The safe bet so far is: go back to raw string manipulation, and 
*keep* the generated code, to be read by human (for inspection) 
and compiled by the compiler in the 2nd pass.

As to the tool for the such string manipulation: it can be:
-- C preprocessor,
-- Python script, or
-- D string interpolation (can I save the generated code?).
