Hi,

I found these slides very interesting, on how python generator patterns can
be used to create re-usable code-parts that can be "piped" togegher ad
infinitum, to create e.g. parsing pipelines requiring minimal memory (things
a sysadmin working with huge files might need quite often):

http://www.dabeaz.com/generators/index.html
PDF: http://www.dabeaz.com/generators/Generators.pdf

It would be nice to do this kind of stuff in D though, to hopefully gain
some performance, so I wonder, is there similar stuff in D, and where to
find info about it?

Cheers,
Samuel

D uses the range concept. Phobos ranges are based on the ideas presented 
in this article:

  http://www.informit.com/articles/printerfriendly.aspx?p=1407357

But some of the design and even the names of range types have changed 
since that article has been written.

These and other Phobos modules make use of ranges:

  http://www.d-programming-language.org/phobos/std_algorithm.html

  http://www.d-programming-language.org/phobos/std_array.html

P.S. I am in the process of translating my Turkish D book to English. For 
completeness, here are the two chapters about ranges:
