It could be made safe by making to_string_t a template and forwarding from_string's argument into its storage, if things are not complicated enough already :) Something like this template <class String> struct to_string

Yeah, this is something that might have made sense before auto, and in fact IIRC there were some Boost libraries that used this trick (Boost.Assign?), but it's just unnecessary complication at this point.

This blog post has a much more in-depth analysis of the cost of overflow checking: https://blog.regehr.org/archives/1384 The tl;dr is that (on x86-64) the additional branch to trap has almost negligible cost (processor

When analyzing complexity, "n" is conventionally the input size. For arithmetic operations it would be the number of digits, not the number itself.

I'm not sure what the point of this post is. It says > And yet at every point in history, there were true things that would get you in terrible trouble to say. Is ours the first where this isn't so? What an amazing coincidence

The machine can only do one test at a time, so throughput = 1 / latency.

Yes there is some concern that it would affect code size and/or make some optimizations impossible, but on the latter I have yet to see hard data that that is the case. We're talking about adding about 1-2 cycles of latency. Note

I wonder if they have considered implementing futexes in userland so they don't have to wait for the kernel implementing this. WebKit has its own implementation (see the ParkingLot in https://webkit.org/blog/6161&#
