File extension of c++ files used on d compiler sources

[Domingo Alvarez Duarte via Digitalmars-d]

Hello !

I'm starting to look at the d compiler sources and I'm using 
netbeans to navigate through the sources, netbeans is very good 
at showing warnings/errors with it's own internal parser, but 
because all the c++ source files use ".c" as file extension they 
are interpreted as "C" files and shows a lot of errors parsing 
then as "C" files.

It could be a silly question but here it is:

Why the c++ source files do not use file extensions that proper 
identifies then as c++ like ".cpp", ".C", ".cxx" ?

This prevent/difficult some task automations by third party tools 
like I'm experimenting now with netbeans.

It's fine that D is innovating in the programming language field 
but not all conventions are bad ones.

Cheers !
