In my own experience, the one scenario where I've desired to have function template partial specialization was when the template parameter is used only as a template parameter and not as a function parameter. Overloads don't help at all for that, but you can of course work around it via a `wrapper` function parameter where `wrapper` is functionally identical to `std::type_identity`.
The trick to replace a primary template is 100% UB because you can't just put stuff in std willy-nilly, but it's incredible that in practice, you can now bring C++ back to the old JS days of just replacing something you don't like. You can't have constraints on non-template functions (yet? didn't follow whether it was delayed or denied), but that would've gotten us pretty damn close, not that the standard library has much non-template code anyway.
Can we please add the overload set pattern into the standard? It's very useful for variant visitation and it doesn't make any sense to keep writing this manually everytime we need this ...
44:00 Note that for user-defined char sequence literals, you also get separator and decimal point characters. For that reason, you cannot simply subtract '0' and add.
10:20 Actually, there’s four ways to express constrained template parameters because you can put a requires clause behind the template parameter list and behind the function parameter list. The second version exists so you can refer to parameters in the constraints (e.g. decltype(param)), but to be honest, I don’t really understand where requires behind the template parameter list really shine.
Hex floating point literals are nuts: static_assert(0xAB.Cp1 == 0x55.Ep2); That is because the exponent is 2-based, not 16-based: static_assert(0xAB.Cp0 == 0xA.BCp4); Can you guess what 0x1.4p3 is?
It's just fine on my monitor. -Get a bigger monitor.- Just kidding. The player should allow zooming in and out. Well, if you really want to, PotPlayer allows to open YT videos and easily zoom in and out, and move the focused part to where you want it.
Yeaaaaaaaaah, this template stuff also doesn't quite interests me, but something digging deep into pointers, SIMD instructions, memory management, etc... would be awesome! Arena allocators? There's some cool trickery when replacing free and malloc
May be my word will be very harmful; i should tell it: These day c++ standard-er need to learn deep concepts of mathematics logics and predicate calculus, topology and algebraic topology; The old way of concept is more better than key word concepts and should be replaced by TheCondition ; Because Concepts should build a fonction or Templates and under the template we write what the conditions should be for the parameter ; the concepts gave a general rule inside class or function {like return type, errors, max_memory or type of execution ……….} . Am y right.
