StackOverflow: Applications development with D language

[Julio César Carrascal Urquijo]

There's an unanswered question on Stack Overflow about D. Anyone cares to 
write a response?

http://stackoverflow.com/questions/289087/applications-development-with-d-language

"""
For those who had developed applications with D,

    * which libraries did you use to build your application?
    * those libraries were good documented?
    * did you use Tango?
    * do you feel that D is ready to build big applications?
    * which IDE did you use? Descent maybe?

      Thanks in advance. Jonathan.
