If recursive templates are not intuitive to you, perhaps you 
still have more D to learn, to become this mythical "D 
programmer".

My 16 lines of template essentially compiled in D for at least 
the past 10 years.
It literally is "regular D code".

If recursion and declarative programming isn't intuitive to you 
in general, then perhaps that's not D's problem at all.
