Ignore the part about Pascal and read the Post by matthieum:
I have, for my company, been part of a group in charge of
exploring the criteria for the inclusion of new languages in
the company's set of supported languages.
Here are some of the comments:
Note that we already rejected D because we did not find it
compelling enough. We are not looking for a 10% better
language; given the cost of adding a language (as alluded
above), which are much more linked to talent management than
technological issues, a new language has to:
either cover an area that is ill-covered today (we added Python
in the last couple years for this, and Scala is being
prototyped for BigData analysis)
or bring a significant benefit it aims at displacing an
existing language
This is part of the issues that D faces. Especially that last
sentence... "bring a significant benefit".
And some other user his responds:
D is now more of a research platform for Walter than anything
else.
Public image is very important ... Its not the first time
stumbling on comments like this.
