Indentation in emacs d-mode

[J-S]

I've tried (and failed) to get my emacs (26.1) to properly handle 
indentation (as per the "D style") in d-mode (2.0.9).

Things that don't work:
- aligning braces below keywords like "foreach", "while", "in" 
etc: when I put the braces on the following line, I get a 4-space 
indent (while the correct behaviour should be: align);
- the "in" keyword itself gets indented 4 spaces w.r.t. the 
function name (I again get a 4-space indent, while the correct 
behaviour should be: align).

class foo {
private:
     real _bar;

public:
     creal bar;

     void fiz()
         in
             {
                 foreach (...



I'm sorry for asking such a stupid question, but can anybody 
point me to a precooked consistent set of customizations?
