If performance plays an important role, I wonder why nobody mentioned
lua. (I did never really work with it but some voices say its quite
fast, flexible and extensible with 'native code').

Also I have the feeling lots of people inseperable connect web
programming with scripting languages.

I see no real reason for not using plain D, maybe with a well-thought
web-framework/library for web-apps. I mean especially web-apps require
a good performance and if you remember that still lot of apps use CGI
it is gruesome to re-load an interpreter every request.

(I know there are lots of coutermeasures you can take against this
problem, I just wanted to show the extreme case)

Concerning security there ARE good reasons why you wouldnt want to
write your webapp in C++ or C, you almost pre-programmed buffer
overflows then. But D is lots more secure by design and if you look at
PHP, you see that a scripting host does not always liberate you from
buffer-overflows or other attacks.

I would love such a framework. I'm also wondering if there might be a
way to avoid that awful stateless coding style, ie to be able to do
something like:

----
ask_for_users_address();
// user gets a form to enter its address, program here is "frozen" here
// until the user submits or the session times out

ask_for_users_bank_account();
// present another form
----
