Yes. I’m not sure how slow it is in Julia, but pure functional languages do tend to generate more garbage for this reason. Hopefully the compiler can optimize it away in simple cas…

I think we’re talking past each other. Lenses serve many purposes. All I’m saying is that in practice, the most common role they fulfil is to act as a counterpart for mutable refer…

Immutability gives you persistence, which can be practically useful. It’s not just fear.

But what’s the benefit of this approach? It seems needlessly expensive, both in terms of computational overhead (walking up and down the state tree) and how much more code it requi…

You know, I do not actually know that a website had ads before clicking on a link to it; I would be happy to only visit websites without ads. It’s scummy to shove ads in my face wi…

Imagine asking the browser on my hardware to do things I don’t want it to do, and acting shocked when I tell it not to.
