alt Hacker NewsYou make a compelling argument, but, empirically, when you optimize code for performance, you end up with an unreadable mess that breaks all abstractions; but every time I've substantially optimized a proof for performance [of proof checking], I've ended up with better abstractions and more modularity.
That's super interesting. I wonder if you've tried optimizing for type-checking duration of a richly dependently typed program and gotten viscerally nicer code out of that.
