> lang that uses byte sized bools

Isn’t that pretty much all of them? The langages where that’s not the case are usually those using pointer-sized bools.

They tried to make this convenient with std::vector<bool> in C++, which turned out to be a bad idea in general.

It should also be pointed out that storing those booleans as bits is not the only alternative. For a trivial example one could have millions of sorted bools and just store how many are true, then storage becomes constant.

It can be done for performance reason I assume. Numpy for instance does that:

https://numpy.org/doc/stable/user/basics.types.html

yes, exactly. Access/modification of a directly addressable byte is much faster than some bit of it. If I'm not mistaken, on Win32 `BOOL` data type is defined even worse to a 32bit int (this C API was devised way before `bool` has made it's way into C), so 8bits isn't even the worst case scenario :D

Can’t believe it’s 9 years old at this point, but I made this for a project a while ago to solve this problem in JS.
