Are there any developer experience advantages for `x := 1` over `let x = 1`? A `let` keyword probably improves parsing error behaviour, and makes declarations more visible. := is more concise though.

After further playing with my LLM project, I'm surprised how hard it is to tune with system prompts. My agent kept saying "obviously" even though my prompt said "helpful, professional". Eventually I found that a "courteous" prompt gets "of course" which is better but not ideal.

I've been tinkering with an LLM interface with my calendar and it's really nice to use. "Delete my April trip" is a lot less fiddly than opening calendar, switching to the month view, scrolling to April and so on. I should probably build an undo as well though.
