Actually I want to serve some JSON packed weather data (heck I 
also wrote my Global Climate Model partially in D and in C) - so 
I guess, I can use vibe.d to build a cgi.

However I also want to recieve some userinput, and parse it - and 
sometimes, php is simpler, because for a very small parsing task 
you dont want to worry abotu types and all. Does vibe.d support 
any HTML Preprocessor in the first place? If not PHP then Neco? 
Falcon? So that I do not always have to access my vibe.d based 
app, but I can simply change the page itself a bit?
