Help to fix D-related issues in Meson build system

[Denis Feklushkin]

Hi!

In my hobby work on porting druntime to another architectures I 
actively use Meson build system. It allows to build huge 
heterogenous projects very conveniently without losing of control 
over fine-tuning.

But at present there are a lot of D-related issues in the Meson. 
In most cases this issues do not appear (many of us use meson 
with D every day without problems), but when you start using 
Meson to its fullest then issues become irritate require lot of 
hard tricks to get around them.

Support of individual languages ​​is not an biggest goal of Meson 
authors, as I understand. In my experience they are rather to fix 
and add functionality that applies to all supported languages ​, 
but not for some one rarely used. As a result, Meson contains 
serious errors related to D that no one tried to fix.

I wanted to appeal to those who were lucky enough to know both 
Python and D: please try to fix D-related functionality of Meson.

Thanks!
