$(D_S D Programming Language $(VER),
$(BLOCKQUOTE Michael,
It seems to me that most of the $(SINGLEQUOTE new) programming languages
fall into one of two categories: Those from academia with radical
new paradigms and those from large corporations with a focus on RAD
and the web. Maybe it's time for a new language born out of
practical experience implementing compilers.

$(BLOCKQUOTE Segfault,
Great, just what I need.. another D in programming.

$(P
D is a systems programming language.
Its focus is on combining the power and high performance of C and C++ with
the programmer productivity of modern languages like Ruby and Python.
Special attention is given to the needs of quality assurance, documentation,
management, portability and reliability.
)
$(P The D language is statically typed and compiles directly to machine code.
It's multiparadigm, supporting many programming styles:
imperative, object oriented, and metaprogramming. It's a member of the C
syntax family, and its appearance is very similar to that of C++.
Here's a quick list of $(LINK2 comparison.html, features).
)
$(P It is not governed by a corporate agenda or any overarching theory of
programming. The needs and contributions of the
$(LINK2 ../NewsGroup.html, D programming community) form the direction it
goes.
)
$(P There are two versions of the language:
$(OL
$(LI $(LINK2 http://www.digitalmars.com/d/1.0/index.html, D version 1)
which is in maintenance mode.)
$(LI $(LINK2 http://www.digitalmars.com/d/2.0/index.html, D version 2)
which is recommended for new projects.)
