Go 2 generics counterproposal: giving up restricting types

"I want to make a generic function which works on any type that satisfies these and these constraints."

When we think about generics, this is the sort of problem that pops up into our minds. The critical part is restricting the set of types our function intends to work on. Trying to solve this problem of restriction has led people to what I call reasons why we hesitate to have generics in Go.

C++ templates with horrific error messages, or even it's new concepts, Java's T extends Comparable<T>, Rust's generic traits, Haskell's type classes, and sadly even contracts from the [original generics proposal by the Go Team](https://go.googlesource.com/proposal/+/master/desig

Minimal D3D11

Minimal D3D11 reference implementation: An uncluttered Direct3D 11 setup + basic rendering primer and API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion that should be easy to follow from the code alone. ~200 LOC. No modern C++, OOP or (other) obscuring cruft. View on YouTube

Also check out Minimal D3D11 pt2, reconfigured for instanced rendering and with a smaller, tighter, simplified overall code structure, or Minimal D3D11 pt3, with shadowmapping + showcasing a range of alternative setup and rendering techniques.

This is a slightly stripped down version from our internal bug tracker. The point of posting this publicly is part FYI, part peer review. I'm hoping someone can look at this, disagree, and tell me all the downsides of using the C locale or point out things I've misunderstood. The Recommendations section in particular is contextualized by our database serving a SaaS product for users from many different locales, thus making locale a render level concern. YMMV, caveat emptor, etc.

The locale settings influence the following SQL features:

• Sort order in queries using ORDER BY or the standard comparison operators on textual data
• The upper, lower, and initcap functions
