Amazing work! I was wondering just a few months ago whether someone ever made a logger that deferred all the expensive work of string formatting to consumption time.

~~I'm a bit surprised that it didn't come along sooner though. How come nobody at Google or VMware who said they noticed this was a problem solved it? Or any other major tech company? I guess maybe this is partially an issue with our programming languages and build tools though? I'm a Zig enthusiast though so in my head it's trivial, but I guess it won't be until C++26 that they get potentially comparable comptime facilities for C++.~~ I'm surprised Go doesn't work like this by default though. For a language like Go, I'd have made a builtin log keyword that does this.

EDIT: Looks like other implementations of similar ideas do exist. Still awesome though!
