I can write scaleAll like this:
auto scaleAll(int[] xs, int m) @nogc {
return repeat(m).zip(xs).map!(mx => mx[0] * mx[1]);

So that repeat(m) stores m, but it is quite hacky to work like
this.
Here's a spoonful of sugar to help that go down easier:

And with some mixin magic you can get syntax like:
int a = 2, b = 3;
xs.pack(a, b).map!(unpack!((x, a, b) => x * a * b));

Of course it sucks that you can't just tell a delegate to capture
by value.
