Is there a skip() function for ranges? I need to skip N elements of a range
and then take M elements. Something like

writeln(take(range, 10), ": ", take(skip(range, 10), 10));

Thanks

No, but this pull request

https://github.com/D-Programming-Language/phobos/pull/147

will introduce the drop function which does that. It hasn't been merged in 
yet though. The closest that there is right now is to call popFrontN, but
you can't do that in the middle of an expression like that.
