> The downside is it needs a brain warm-up, and this is per project, but once that flywheel is spinning, I find it almost effortless to write code.

How is that different from other languages, which don't need the brain warm-up?

The difference, if you split hairs, that the brain warm-up takes a bit longer. Maybe a couple of hours, or a day at most.

Otherwise it's not different for me. I don't feel different while writing with any other language. I guess the main reason is I always think like the computer first and translate that thinking to the programming language at hand.
