What do I have to do, to make this work?

iota(number).each!...command_x(a...);command_y(b...);command_z(c..))

You can use it like this:
iota(10).each!((x) { command1(); command2(); ... });

I missed this syntax!

Or there is a short syntax (lambda):
iota(10).each!((x) => command1());

See http://dlang.org/spec/expression.html#Lambda for more info about lambdas.

Or is there something like number.times!{....} possible?

You can write your own function. It is simple.
void times(alias fun)(size_t i) {
        foreach(unused;0..i)
                fun();
}

and use it like this:
10.times!({ writeln("yaaay"); });

Thank You! Ali and Anton!
D is so cool! :D
