What's wrong with doing it in two passes? N iterations each doing 2 operations is exactly the same cost as 2*N iterations each doing 1 operation. Because multiplication is commutative.

Python's pytest framework achieves this without macros. As I understand it, it disassembles the test function bytecode and inspects the AST nodes that have assertions in them.

Definitely. Once you aren't adding new features, the only thing left to do is fix bugs. New rewrites can make the same old mistakes. But there is the potential to have a lower "bug floor" in a safer language.

it's not a multiplication. decimal points used to levitate in those days.

Energiewende is a failure in both technical and economic senses: half a trillion euros spent to get a more expensive and less reliable power grid, and a fleet of perfectly functional nuclear power plants were spitefully binned.

But you still need to choose a significance threshold, which is just an opinion. There's nothing "scientific" about p=0.05; surely God loves p=0.06 almost as much.

They'd be perturbed a little but it's not like they'd go colliding into anything. It's not a big deal; shell theorem applies.

You disassemble a planet for the raw materials. Mercury would do. The real problem is that Dyson spheres are wasteful because stellar fusion is thermodynamically inefficient. If you harvest the material of the star and fuse it yourself, you

For one thing, before this decade is out we will have the lift capacity to get an ELT-worth of mass to L2. And the lack of need to correct for atmospheric distortion would simplify the design considerably. But it's beside the point. Su

No I don't think it's about compactness of expression, but rather what it's possible to express at all.
